Wireless RGB LED Controller Using 433MHz RF Modules and Arduino

Projects that involve wireless data transmission are always a lot of fun – as well as projects that invole RGB LEDs. So today we will combine the two and build a wireless RGB LED controller using two Arduino Nanos and one of these cheap 433MHz RF transmitter and receiver kits. The project consists of two parts: The transmitter circuit and the receiver circuit. On the transmitter side there are 3 potentiometers that can be used to set the red, green and blue values for the RGB LED. The Arduino then constantly reads the analog values from the potentiometers and sends...
