Being very new to Arduino and the world of electronics, I've started playing with a few projects and I think I'm ready to move to a little bit more complex projects. Over the weekend, I was thinking about how to drive a DC motor using the Adjustable Breadboard Supply. I've done with with a very small servo with no isolation but now I'm considering a bigger motor (6V).
Can somebody help me with some questions?
- Can I drive the motor from the high voltage side?
- I'm using an opto-isolator to control the DC motor. Can I ground the regulated side to the Arduino or do the sides share a common ground?
Thanks in advance!
