Electronic systems can help the visually impaired. This project combines an Arduino Nano, a TCS34725 color sensor and a buzzer to assist color blind users.

They’re using a cheap sound sensor module and an Arduino to catch instantaneous photographs, with students caught in the act of popping balloons.

Inside you’ll find an Arduino board, microphone, and an 8×8 RGB module. The front cover of the project box diffuses the light using a sheet of tracing paper on a frame of foam board.
