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.

We’d seen it done with buttons, switches, gestures, capacitive touch, and IR remote, but never like this. [electron_plumber] made an LED that can be blown out like a candle, and amazingly it … ...
