Building the Fidget Spinning Robot The fidget spinning robot is a fascinating project that leverages a couple of servos together with an Arduino development board and a few 3D printed parts.

It was built using parts from a floppy drive and a cdrom, as well as an Arduino and a small wireless transceiver. Using an IR sensor to detect rotations, the Arduino sends data to the LEDs.

The earliest televisions used a spinning disk technology called the Nipkow disk, which is exactly what [Science ‘n’ Stuff] recreated with their Arduino-based mechanical color television (video ...
