This is a Knight Rider LED Light and it is one of the best Arduino projects for beginners. This board drives 16 high-power LEDs to turn them ON one by one sequentially. This is an open-source Arduino compatible project that contains 16 high current MOSFETs, Atmega328 microcontroller, 5V regulator etc. The gate of IRLR7843 MOSFETs is connected to the I/O pins of the Atmega328 chip. Screw terminals are provided to connect the LEDs and power supply. Additional 2 x tactile switches and one connector for analog input are provided for further experiments. Operating power supply 12V to 15V DC, each output can drive 1A constant current load (1W to 12 W LED) without cooling and load up to 2A with forced cool air.
