Researchers from the University of Johannesburg in South Africa have developed a cleaning system for solar modules based on the TCS3200 color sensor and the Arduino Uno open-source microcontroller.

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

So Charmed Labs and Carnegie Mellon University teamed up to create a cheap and efficient vision sensor, and Pixy was born.

You can actually build your own color-sensing lamp with this $8 Adafruit RGB color sensor, and follow along with plenty of Arduino tutorials online. But look how cool and sleek its product video is!
