William Pennings built this wonderful machine that automates the arduous but necessary task of sorting M&Ms and Skittles by color. (Insert Van Halen joke here.)
"It's pretty quick and sorts about 2 pieces of candy per second" Pennings says. "It uses Arduino microcontrollers and stepper motors for quick and precise movement. A TCS34725 color sensor performs the measurements. Furthermore, the device is equipped with LEDs in several spots which nicely complement the overall look of the machine."
