M5Stack's success is inextricably linked to our community's support, and we thank you for it. We wish you a Happy New Year! We will continue to provide more and better services to meet your needs in the coming year.

 The Build2gether Inclusive Innovation Challenge, hosted by Europe's top university ETH Zurich and organised by the world-renowned hardware community Hackster.io, recently concluded. The competition, in collaboration with partners M5Stack, Google, Blues, PCBWay and Useful Sensors, offered a total prize pool of $40,000.

This global competition aimed to encourage people to use innovative technology to help individuals with physical disabilities overcome challenges in their daily lives and build a more inclusive and equitable future. The competition received a total of 194 submissions, with many participants choosing M5Stack products. In this blog post, we have selected some of the award-winning projects to explore the development stories behind them!

 1.Haptic Vision Assist

This project uses M5Stack's controllers and sensors to provide simple, cost-effective and efficient obstacle warnings using infrared laser and haptic technology to visually impaired users to aid their mobility.

The author, Colonel Panic, witnessed the daily challenges faced by visually impaired people while living with his fiancée and her son, both of whom have inherited Retinitis Pigmentosa, a genetic eye disease. Motivated to help improve the lives of visually impaired people, Colonel Panic learned to use M5Stack products and UIFlow within a year. To quickly become proficient in the use of M5Stack, he challenged himself to create a prototype for a new idea every day.

2. Wall Early Warning System for Swimming Laps

This project uses Bluetooth beacon technology to warn visually impaired users when approaching the pool wall, preventing accidental collisions due to poor visibility while swimming.

Have you ever hit a wall while swimming? What about doing the backstroke? Ouch! Now imagine having poor eyesight; everything becomes even more challenging! Inspired by personal experience and discussions with disabled mentors after joining a competitive group, author David Barrett came up with the idea for this project.

 3.Intercom and Smart Controller Mounted on Wheelchair and Roll

This project allows people who use wheelchairs or walkers to receive real-time doorbell notifications via Telegram, see who is at the door, and remotely control door access.

Imagine hearing the doorbell ring and feeling nervous. You might even rush to open the door. These actions may seem simple for able-bodied people, but they are inconvenient for people who use wheelchairs. This project effectively addresses this pain point.

 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.

 5. Cracked road detection for better travel

This project can help people who use wheelchairs to be aware of road potholes in advance to avoid accidental falls while travelling.

One of the challenges faced by wheelchair users is encountering cracked roads, where if the user is not concentrating, they could fall into a pothole and potentially injure themselves. Hendra Kusumah aims to create a solution that is easy to build and program, requires no soldering, and costs less than $50.

6. Cheza Pona

This project is an innovative gaming platform that redefines inclusive skill development, specifically designed for people with disabilities such as cerebral palsy and muscular dystrophy. Cheza Pona provides dynamic and adaptive gaming experiences.

According to a 2017 study by the World Health Organization, only 1 in 10 people with disabilities in low-income countries have access to the assistive technology they need. In response to this challenge, Ryan Kiprotich and Mergery Wanjiru proposed a solution called Cheza Pona, which means "play better" in Swahili. They transformed the typically monotonous physical therapy into an enjoyable gaming experience. Using the low-cost M5StickC, they created a game where players can use the built-in inertial measurement unit sensor to move sideways and avoid blocks in the game to score points.

7. Move-It!

This project turns M5StickC int to an IMU-based gaming device - a small wearable device whose movement can provide input to games.

The project was mainly aimed at developing something small which can help people with Muscular Dystrophy play games without over-exerting and tiring out faster. I won the M5Stack Gift card and ordered the M5StickC and a mini dual button unit. The idea was to use IMU input from the M5StickC as serial data and process it as keyboard input.

Modular IoT system construction offers high flexibility and scalability as the developers can quickly build prototype systems using existing modules to save time in design and development. It assists developers in swiftly developing and validating their concepts and works directly from idea to product, allowing developers to create various types of devices and solutions more quickly and economically.

M5Stack’s products have a stackable design, providing standardized interfaces for easy construction of the system, when combined with the intuitive visual programming interface of UIFlow, it significantly reduces the technical barriers of system design and development. Even developers with limited hardware and software knowledge can quickly build powerful IoT devices.

Setting up the UIFlow Environment

Taking the MStack Basic as an example, the first step is to refer to the UIFlow firmware burning tutorial and download M5Burner to burn the UIFlow firmware to the controller.

Building an IoT System

If we need to detect air quality. We can stack the PM2.5 Air Quality Module  to the MStack Basic.

Then, in UIFlow, click on "PM2.5" and select "Load Examples" to open the sample code.

Click "Run," and we will see the air quality displayed on the screen.

When we want to drive a stepper motor to actuate certain mechanisms when the PM2.5 concentration is high. We can stack the GRBL  Module.

 

Next, find the code blocks corresponding to the GRBL module in UIFlow.

Set the motor drive mode at the beginning of the code, here we set it to distance mode.

In the main loop of the program, add a condition based on the PM2.5 concentration, using the value stored in SP for simplicity. When the concentration exceeds 55 (μg/m³), the stepper motor starts rotating. When it falls below 55, the stepper motor stops rotating.

Click "Run," and the system will operate as we set.

Conclusion

In summary, the stackable modular design provides a flexible, efficient, and scalable approach to IoT system development. When combined with the visual and user-friendly programming environment of UIFlow, it makes system construction easier, reduces development costs and risks, and facilitates rapid prototyping and feature expansion.
