Smart Juggling Balls is a project of mine which consists of 3 basic modules: arduino pro mini (compatible) MPU 6050 and nrf24 and a bunch of LEDS of course :) The files I publish include the PCB manufacturing Gerber files STL files for the casing (ment for 3d printing) and some code I wrote. The idea is to have colorful and happy juggling balls which can change lightning based on the sensor readings and remote maniputations communicating via nrf24.
Build enjoy and share.
