i am working on a project where i am disassembling an RC Car and using its parts for my robot.
i will replace the built in microcontroller with an Arduino Mega 1280.
i am concerned with how to run the motors, since the arduino only provides 40ma of current per pin.
i do not know how much current the motors will take, but the car moves at 5mph.
what would be the best way for me to supply sufficient current to the motors?
