Hi! I'm new to robotics, so hopefully I'm missing something easy.
I'm using the Parallax, Inc. Robotics with the Boe-Bot book for my AP Physics 1 class. I learned how to use the servos and centered them using a screwdriver. They seemed to work fine at first - they ran code as expected, anyway - but I put them away for the day, came back during the next day's lab, and one of my servos refused to turn.
I know it gets an electrical signal because it twitches when I turn on power, but then it won't respond to any code. On top of that, I did a silly thing: When I was first troubleshooting, I tried the only thing I knew how to do, which was adjust the potentiometer. This didn't fix anything. So now the servo is un-centered and not moving; I suspect the one is fixable as soon as I fix the other, but it isn't what I wanted.
Can anyone help me get my servo moving again?
