 4. Motion Controller for People with Limited Arm Function

This project focuses on developing a motion controller for gaming purposes specifically designed for individuals with limited arm function due to conditions such as muscular dystrophy. For PC gamers, the mouse is a crucial peripheral device. However, mice require a flat surface to function properly and demand users to sit in front of a desk, constantly extending their arms, which can be challenging for some individuals with disabilities.

Therefore, Yahya Khalid created a simple controller using the compact AtomS3, which can effectively replace a mouse. With this device, users can adjust sensitivity to meet their specific needs, and hand position or orientation is not limited, accommodating individuals with restricted hand movements.

Last December, we covered some new products from M5Stack, one of which is the Atom S3. We got our hands on this compact device from M5Stack, and now let's write a few sentences about its introduction. In our article about M5Stack Core2, we mentioned that M5Stack's concept is to combine different microcontrollers, screens, sensors, and actuators through stacking to create a variety of completely different devices. Atom S3 also follows this principle.

This is an incredibly small device, measuring 24×24×13 mm and weighing only about 6.8 g. Without requiring any additional components, it can be used as a stand-alone unit (node) or as part of a larger system to perform various tasks. In fact, Atom S3 provides almost all the necessary functions to act as a control device. The core of this tiny Atom S3 is the ESP32-S3FN8 microcontroller from Espressif. We have previously written about the ESP32-S3, which features a dual-core Xtensa 32-bit LX7 processor with a clock frequency of 240 MHz, 384 kilobytes of ROM, 512 kilobytes of SRAM, and 16 kilobytes of RTC SRAM. Atom S3 sacrifices additional flash memory storage due to its size. With a 3D metal antenna, the Atom S3 can connect to a 2.4 GHz local area network, supporting the 802.11b/g/n standard with data transfer rates of up to 150 Mbps, and supports Station, SoftAP and Station+SoftAP modes.. The Bluetooth version of ESP32S3 chip is 5.0 and it also supports Bluetooth Mesh, making it convenient to communicate with other devices in the network. The data transfer rate of Bluetooth is also noteworthy, reaching up to 24 Mbps per second.

Despite its small size, Atom S3 offers quite a few peripheral devices. The first thing that catches the eye is a compact 0.85-inch LCD screen with a resolution of 128×128 pixels, which is connected to the ESP32-S3 via the SPI interface. The model of this screen is N085-1212TBWIG06-C08. We don't have much data about it, but we can confirm that the display quality is excellent. In fact, ATOM S3 consists of two PCB boards, forming a sandwich structure, with the smaller PCB located below the screen, carrying the MPU6886, which is a high-performance six-axis MEMS motion tracking device and a 6DOF (Six Degrees of Freedom) device. The MPU6886 combines a three-axis accelerometer and gyroscope with high precision and sensitivity. It is connected to the ESP32-S3 via I2C. Previously, we obtained a small add-on board called M5GOBottom2 with an MPU6886 together with the M5Stack Core2 kit. Inside ATOM S3, there is also a green LED (WS2812 RGB LED) and an IR LED (infrared emitter/transmitter).

Atom S3 can be connected to a computer using a USB-C connector, and it's worth noting that the ESP32-S3 has a direct USB port (CDC function) for programming through that port. AtomS3 is usually powered via USB-C (but can also be powered through the header connector), and the voltage regulation is handled by SY8089, which is a step-down regulator that allows an input voltage range of 3.3V to 5V and provides a maximum current output of 500mA.

In the Atom series of products, the bottom-exposed pins can be defined for functions such as I2C, SPI, UART, GPIO, and ADC. There is an expansion header connector called ATOM-MATE, which allows users to connect to other sensors, actuators, or external devices to expand the usage range by accessing the pins on the bottom of Atom. Additionally, Atom S3 has a programmable button and a programmable RGB LED that can be used for user interaction and status indication.

Atom S3 supports Arduino IDE, MicroPython, and UIFlow, which allows developers to write applications using familiar development environments and languages and leverage rich libraries and resources. M5Stack provides extensive documentation, sample code, and tutorials to help users get started and develop their own projects.

CoreS3 is the third-generation flagship product of the Core series controller launched by M5Stack. Compared to the previous Core2, CoreS3 brings more innovation and functionality. Through the continuous release of new products, M5Stack has proven that its products are not only suitable for electronic enthusiasts' projects but also widely applicable to industrial and commercial projects, providing an excellent foundation for training future engineers. CoreS3 is a strong testament to this. So what are the new features in CoreS3 compared to Core2, which was released two years ago?

If we compare them side by side, we will find that the dimensions of Core2 and CoreS3 are basically the same. In fact, if we ignore the color, their casings are identical. Of course, the difference lies in the hardware configuration, although there is some overlap in certain details.  Similar to the chip used in the Atom S3, which we have already mentioned several times, the M5Stack CoreS3 uses the ESP32 S3, a microcontroller from Espressif Systems.

Let's briefly review the basic features of the ESP32 S3. ESP32 S3 is a dual-core microcontroller that utilizes the Xtensa® dual-core 32-bit LX7 processor and supports 2.4GHz WiFi and Bluetooth functionalities. It offers a maximum of 16MB of optional Flash and a maximum of 8MB of optional PSRAM, sufficient to meet the requirements of any task. Users can transfer programs to the CoreS3 via the USB-C interface, which also supports OTG and CDC functionality. The USB-C interface can be used for both power and battery charging.

CoreS3 still features a 2-inch capacitive IPS screen with a resolution of 320x240 pixels. The glass screen is scratch-resistant and is equipped with an ILI9342C driver. The touch function is carried by the FT6336U, which is the same as Core2. While there isn't much difference in the screen between CoreS3 and Core2, there are significant differences in the functionality underneath the screen. Core2 only had three touch-sensitive areas underneath the screen, whereas CoreS3 is equipped with two microphones, light and proximity sensors, and a camera. In terms of audio, both devices are I2S devices with 1W power speakers, but CoreS3 has an ES7210 as a 24-bit audio ADC and an AW88298 audio amplifier. For the light and proximity sensor, CoreS3 has chosen Liteon's LTR553ALSJ proximity sensor, which can measure a range from 0.01 lux to 64K lux with a 16-bit resolution. The proximity sensor consists of a standard LED (emitter and receiver), and users can determine the distance using an 11-bit resolution. Lastly, CoreS3 also features a GC0308 camera with a 300,000-pixel sensor. The camera sensor has a 10-bit ADC resolution and supports VGA video at a maximum of 30 frames per second.

The CoreS3's metal casing hides even more interesting sensors. For accelerometer and gyroscope sensing, it features the Bosch BMI270. The BMI270 offers a 16-bit resolution for six-axis sensing. If you thought there should be a compass sensor next to such a sensor, M5Stack has already taken the lead. On the CoreS3, it also houses the Bosch BMM150, a three-axis magnetometer sensor with a resolution of 0.3 μT. But that's not all. Next is the BM8563 RTC, capable of displaying seconds, minutes, hours, days, months, and years. It supports both 24-hour and 12-hour formats, as well as leap years. For each mentioned integrated circuit, available interrupt pins are utilized. Specifically, for the RTC, the CoreS3 can be programmed to set an alarm, making use of this functionality.

On the side of the device, CoreS3 retains the microSD card slot, reset button, and power button. Next to the USB-C interface is the I2C PORT.A. CoreS3’s bottom provides access to a 2x15 pin header and a JST battery connector. It is worth mentioning that the AXP2101 is used as the battery management chip, which is a high-performance power management chip that utilizes advanced integrated circuit technology to provide comprehensive power management functions. On the bottom of CoreS3's metal casing, there are very small but clearly visible markings that show the internal connections of the ESP32 S3 with the entire hardware. Due to the similar pin layout and compatibility with the JST connector, the Core3's Din Base is compatible with Core2, allowing for full hardware support from Core2.

DIN Base is the default base of Core S3. This base is designed for mounting Core S3 on a DIN rail or a flat surface and comes with necessary plastic clips. The base provides additional expansion capabilities internally. The focus of the DIN Base is power management, allowing Core S3 to be powered by a voltage of 9 to 24 volts through a DC connector using the SY8303 voltage regulator. The 500mAh lithium-ion battery is located beneath the prototype PCB board and is managed together with the TP4057 integrated circuit. The power supplied to Core S3 from the base can be turned off using a small switch. The PCB board itself is a prototype board with plated through holes (PTH) that allow for the addition of hardware according to the user's needs. The side of the base casing has holes for adding additional openings for connecting probes, connectors, and so on. There are also two additional connectors, PORT.B and PORT.C, with pin mappings that are compatible with all Core series devices. Yes, the DIN Base can also be used with previous Core series hosts (all M5Stack components are mutually compatible). We also noticed three holes that allow the base to be used with the LEGO system, which has great potential among children.

The Core series controllers have multiple bases to choose from. Some of these modules are terminal bases, which are dedicated to forming complete devices with the Core, while other bases are universal, allowing them to be used with any controller from the Core series. We would like to specifically introduce the following:

AC Power Base: It allows the device to be directly connected to an AC power source.

2Relay 13.2 Module: It utilizes an STM32F030 microcontroller to provide two relays that can be controlled by the controller.

BaseX (EV3 Motor):  It can connect RJ11 LEGO motors and two servo motors, making it ideal for robotics projects, and can also be equipped with an additional microphone.

LAN Base: Based on the W5500, it allows the host to be connected to a local network via an Ethernet cable, enabling it to be used as a PLC device. This base also comes with RS485 and RS232 adapter boards.

These are several available types of bases, each with different functionalities and features to meet various application needs.

What about the software aspect?

The Core S3 comes with pre-installed firmware that allows for the use of all hardware features through eight built-in applications. These applications include scanning for available local networks, listing the contents of a microSD card, checking the sensitivity of the touch screen, and scanning I2C lines to test all sensors and functionalities on the device. The most notable application is the camera app, which combines the camera function with light and distance sensors. Considering the capabilities of the camera and screen, the camera display on the screen is quite impressive, and we are satisfied with its performance. Two bar graphs on the right side of the screen display the light intensity and proximity, such as the proximity of a finger.

M5Stack has prepared some new features to support the Core S3, and one of them is EasyLoader. It is a small tool used for quickly erasing or writing firmware to the Core S3. Assuming the user program has already been written in an editor, it only requires selecting the port and baud rate values.

M5Stack controllers support large software packages for the Arduino IDE (which takes a long time to download from the internet), and M5Stack also provides support for these controllers. Regarding the added support, we have mentioned it in a previous article about the Core 2. For this ESP32S3 device, the provided support includes some examples. However, in the custom library section, there is a large group of examples prefixed with "M5," most of which are grouped according to the available bases for each Core. Each group provides several examples, resulting in a total count close to three digits, so listing all of them wouldn't make sense. Additional examples not included in the support package can be downloaded from the official GitHub page. These examples are up-to-date and are expected to appear in future updates of the Arduino IDE support. Overall, there are so many examples available for each feature of the Core that there are hardly any scenarios left uncovered.

UIFlow 2, which supports all the latest devices from M5Stack, including the Core S3, has been introduced in previous articles about M5Stack devices. This "blocky" editor consists of three parts, with the ability to hide some parts for clarity when needed. The use of blocks is increasingly popular and may be the best choice for inexperienced users, especially children, as it guides them into the world of electronics and programming. When the curtain is lifted, Python code is revealed beneath the blocks. The third part of the editor is the Python editor itself, allowing complete device programming through Python without the need for block programming. The Python structure used here is largely similar to programming languages used for Arduino platform code written in C/C++. The M5Burner mentioned earlier can also be used here, but it does not support UIFlow, which means that programming through the M5Stack system without a wired connection to a computer is not possible. The tool provides some examples, including the factory examples that come with the device.

Considering the features offered by the Core S3, its price is reasonable. Additionally, by adding modules, it can provide even more functionalities to meet different needs and expectations. Imagine the power of hardware with a screen and direct data input capabilities, along with additional built-in sensors and countless sensors that can be added through ports. It is evident that the possibilities for combinations are limitless, and the Core S3 can serve as a control unit for a larger system or as the central unit of its own system. It can be used in conjunction with the LEGO system, which is an additional advantage. If you want to introduce children to electronics and programming through games and building with LEGO blocks, we believe this could be the right choice. We wholeheartedly recommend it.

As a partner and supplier of software and hardware for this course, M5Stack is thrilled to see the creativity and enthusiasm of the students and believe the benefits of this course go beyond improving learning and increasing students' employability since it also creates opportunities for future technological advancement that will make the world better.

In the following paragraphs, we will introduce the top teams' projects and show how they have used M5Stack's technology to create amazing solutions for some of today's most pressing challenges.

Smart Energy Efficient Urban Farming  

Electricity tariffs in Singapore are rising, and research has shown that factors such as artificial light, plant competition, overwatering and humidity can affect plant growth in urban agriculture. In light of this, this project aims to develop sustainable and energy-efficient practices to address these challenges and promote environmental sustainability in urban agriculture.

To achieve this, the project includes several innovative technologies, such as a height checker that uses a TOF sensor to measure plant growth and plots the data on a dashboard. An automated sunroof adjusts the amount of natural light entering the greenhouse using a light sensor, while a moisture sensor monitors soil moisture levels to prevent overwatering. The project also features an air conditioner that uses the ENV II Unit to regulate temperature and humidity levels in the greenhouse.

PEST TERROR

Urban farming has become an increasingly popular way for people in urban areas to grow their food, but it also comes with its own set of challenges, including pest management. Traditional chemical insecticides can be harmful to the environment and can contaminate the food grown, making it necessary to develop alternative pest control methods.

This project aims to address the challenge of pest management in urban farming without relying on human intervention or chemical insecticides. The project utilizes  M5stack’s iot controllers and sensor, to simulate an automated pest control system that could be developed to effectively manage pests in urban farms.

It includes an antenna system and a robot to detect and eliminate pests. The antenna system has an automated water sprinkler that sprays garlic-infused water, which is a natural repellent, and produces ultrasound waves that some pests find irritating. If a pest that is resistant to garlic water and ultrasound is detected, the antenna system signals the robot to eliminate the pest.

The robot acts as a natural deterrent to birds and has flashing lights and vacuum guns to eliminate pests. The project offers an alternative solution to traditional chemical insecticides and promotes natural pest control in urban farming.

Bee Integration into Commercial Urban Farms

Many commercial urban farms are closed systems, meaning there are no natural pollinators such as bees, butterflies, and birds to provide pollination to crops that need it. This can result in inefficient manual pollination methods being used, which may decrease crop yield and quality.

The project aims to solve the issue of pollination in commercial urban farms by using sensors to integrate bees into  farms and optimize pollination rates while tracking the health of bees automatically.

To achieve successful integration of bees, the project focuses on two key areas: high crop yield and automation. The solution for achieving high crop yield involves a checkpoint system that counts the number of bees and manipulates their movement to achieve optimal pollination rates. The solution for automation involves using sensors to monitor the temperature and humidity of the beehive and indicating the health of the bees using an LED.

Urban Farming Overseer

Challenges in urban farming include fish deaths due to toxic ammonia levels from fish waste, difficulty growing certain foreign plants due to inadequate weather conditions, mass crop deaths from inconsistent watering in soil-based vertical farms, increased expenses and prices due to manual monitoring of plant and fish health, and reduced crop yield from pest and disease outbreaks.

This system helps urban farmers remotely monitor internal conditions in their farms without needing to manually do it themselves. By measuring ammonia levels in fish farms, moisture levels in soil, and overall temperature and humidity, Urban Farming Overseer allows farmers to quickly identify suboptimal conditions and notify personnel to arrange for more efficient maintenance.

on March 6, The International Innovation Policy and Practice Conference was held in Shenzhen, China. Aiming to promote the establishment of the World Innovative Cities Cooperation Organization (WICCO) and build a platform for exchange, cooperation and resource-sharing among the world's leading innovative cities, this meeting brought together in Shenzhen mayors of some of the world's innovative cities, heads of famous technology enterprises, research institutes and venture capital institutions, and representatives of international organizations in China to discuss innovation, seek cooperation, and build an international innovation ecosystem.

Takasu Masakazu, a world-renowned maker, visiting lecturer of Waseda University, and partner of Switch Science Inc., elaborated on the development history and advantages of Shenzhen's hardware supply chain industry and introduced the characteristics of Shenzhen as the world's "Silicon Valley of Hardware". Notably, in his speech, Masakazu Takasu devoted nearly a quarter of his speech to introducing a Shenzhen-based open-source hardware company, M5Stack, to the audience.

What's so special about M5Stack, a company with such a strange-sounding name at first glance?  And why is it being showcased to represent Shenzhen-based open-source hardware companies?

Founded in 2015, M5Stack is a famous Shenzhen-based startup. In Japan, M5Stack is a popular presence among makers. There are 44 operation guide book books about M5Stack on the Japanese Amazon website, and many Japanese companies, universities and colleges use M5Stack for prototyping, validation, teaching and working.

Additionally, many makers all over the world have come to love M5Stack because of its plug-and-play, modular, adaptable, and stacking capabilities. M5Stack also partners with major companies in the industry like Microsoft, Sony, Ericsson, Amazon Web Services, Foxconn, and Siemens.

Link the World by Open Source - the Story of M5Stack

01 The idea

The story of M5Stack began with an idea from the founder Jimmy Lai. He was leaving Southern Grid and found a pile of discarded development boards in a drawer in his studio, which had become useless after having proven the product's functionality. In Jimmy’s opinion, these traditional development boards, with their exposed circuit boards and wires, were not only "crude" in appearance, but also complicated to operate and not conducive to further expansion.

And for individual developers, it can be costly in terms of time, effort and money to turn a rudimentary prototype based on a development board into a product that can be used in everyday scenarios.

"How about developing a modular development kit that could assist developers in swiftly developing and validating their concepts and working directly from idea to product," Jimmy Lai founded his company based on this notion.

02 Open source product system 

The "Stack" product, which has a modular design and a standard size of 5 cm by 5 cm, is plug-and-play, stackable, and extendable. Users can stack the modules with various functionalities to speed up product verification and development, and as a result, "M5Stack" was created. Today, M5Stack has 300+ SKUs, covering the full range of products from embedded controllers and communication modules to sensors, with high performance, reliability, scalability, and quick access to cloud platforms like Azure, and AWS.

03 A convenient graphical platform-UIFlow

Hardware development can be simplified by modular design, but software programming is still a challenge for most individuals. UIFLOW, a low-code graphical programming IDE, was introduced by M5Stack with this problem in mind to offer the greatest experience for prototyping IoT applications from entry-level hobbyists to experienced developers. With UIFLOW, a user can construct a solution out of a single block or use many blocks to achieve more complex scenarios. 

04 Community operations and rapid development

On social media platforms and communities, M5Stack always shares new ideas and real-time product development processes with the fans and makes quick adjustments based on the inspiration and feedback from the users. As a result, it has promoted a positive community culture, with many users regularly offering their thoughts, open-source projects, and practical advice. This has helped to shape what M5Stack is today.

IoT has reshaped our world in recent years as a technological revolution. With the development of IoT, M5Stack has gone through six years. The year 2022 is eventful. Here, we look back at the most important events of this year and express our sincere gratitude to our customers and friends.
