Hello--
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!
Jahrel

You mean the VIN on the breadboard supply? Assuming that the supply that is feeding it is adequate, yes.- Can I drive the motor from the high voltage side?
Both sides of the breadboard supply share a ground.- 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 for the reply!

Exactly. In this case, I only need the usual protections, right--a diode to prevent back surge and so on.You mean the VIN on the breadboard supply? Assuming that the supply that is feeding it is adequate, yes.
Okay. So an opto-isolator won't make a difference and I still have to ground the regulated side to the Arduino.Both sides of the breadboard supply share a ground.

Yes. A diode is a good precaution.I only need the usual protections, right--a diode to prevent back surge and so on.
