ATMEGA328P onboard control for 3 DC brushed motors. This is my version of a control board for this project from Make Magazine. It uses dual H-bridges ICs (SN754410) to drive each motor (channels are doubled for up to 2A continuous current per motor, 4A peak for very short times). Power LED. Also 8 LEDs run by a 74LS595 shift register for “blinky” fun! Photoresistor allows for a laser hit to be detected and affect the omnibot.
This board has been successfully built and tested. It needs an extra +5V/GND header added to provide power to the RC receiver (and servo).
