integrated circuit How do I control a two 12VDC 10A motors using an Arduino

Posted on Feb 7, 2014

Control the state (on/off) and direction of two linear actuators that are really just DC motors. It seems easy but the problem is that the linear actuators are each 12VDC and consume 10 amps of current at full load. I bought a 25A external power supply because obviously the arduino microcontroller cannot not provide that much current. I saw something about using an H bridge to control each motor`s direction

and then I read something about using a relay that acts as an electromechanical switch to draw current from the power supply. Can someone help me out or draw me a circuit diagram of what this looks like so I could be able to put it together I would love to know how all of this works and I know it is probably challenging to beging electronics with but I am willing to learn as much as I can about this stuff.
