Having started the course on 26 projects, I need to know what kind of motor controller I need for a 12VDC motor that is rated at 5 amps with a peak load limit of 25 amps.  This is for an Arduino.  I’ve looked at power transistors,  H-bridge descriptions and controller boards themselves, but my needs are not so demanding, as there’s no requirement for my project that the motors be bi-directional, thus no switching needed.  I need a configuration that supports two motors whose speed(s) can be individually controlled.  What’s your recommendation and your reasoning?  Thanks,
