I'd like to control a small DC motor pulling from a 7.2V battery using a switching transistor connected to one of the EZ-B digital ports and wanted to be 100% sure I was doing this properly. I think the way it works is that I connect the base of the transistor to the PWM pin of one of the Digital Ports, the collector to the positive lead of my battery, and the emitter to the DC motor, right? Also, which transistor should I be using?
Speed controllers come with voltage controls and some more protections for the motor, battery and ez board
Happy building!
