Hey guys, for a project, i want to be able to power 4 DC motors.
Motor rated voltage: 7.2V
Motor stall current: 2.5A
I only need these to go one direction but I want to be able to control when each motor stops and starts. I’ve heard transistors are the best way to go for this. If it is, do I need a transistor for each motor? and then connect each base to an output pin on the arduino. Are TIP122 transistors good for this?
Also do i need a potentiometer for this? if so is one enough?
