This is an easy-to-make LED dimmer using RF remote control. The project is capable of driving a load up to 24W (2A X 12V LED). Any 12V single or 12V LED strip can be used. This is an open-source Arduino compatible hardware that has Atmega328 microcontroller, Potentiometer, MOSFET, 5V Regulator, 3.3V Regulator, NRF24L01 Radio modules, and few other components. The same PCB can be used for Transmitter and Receiver. LED D2 Power LED, LED D1 optional.
