How do I power an UNO and two servos with a wall wart? Answered
I have a project that I want to power with a wall wart (6v 2A). The project is a "Useless Machine", so it's not a complicated project. It uses 2 standard servos and one micro. I have searched a LOT, but I'm unable to find out how to properly do this because most projects use batteries. I know the motors and the UNO need to be powered separately. I thought I could simply splice and connect the 6 volts from the adapter to VIN, and also connect 6 volts to my servos, and tie the grounds together. And that worked for a little while. But then it quit working. Now I have >3 volts going to both my Arduino and my V+ line to servos unless I disconnect one. I honestly don't know which way to go at this point, so I'm reluctantly posting this question. I would appreciate any direction.
