Can you build an RC remote controller with just an Arduino Uno and a random Wifi module? That is the question this project video answers! Clem got visited by his friend Goofy who is driving RC crawlers in a local trophy series and tasks him with improving his current controller by adding more analog channels and open firmware to allow competitors to freely mod their systems. Clem only uses parts commonly found in a makers workshop such as an Arduino Uno, shift registers and some wifi modules to build an RC system from scratch. While it works, he cuts some corners to get latency down, and shows you how to get different microcontrollers to talk to each other over UART and WiFi.
