Power on Arduino UNO
April 8, 2012
Well, I am making a 4 legged robot, this one http://letsmakerobots.com/node/31902. I have already written the code for moving forward, even that I am still expecting some parts. The code works well, the servos are moving well, but just with the power source by the computer, via the cable USB. When I put a battery, it doesn't work at all. Could you suggest something that couldn't work well?? I checked the connections, they are all well. The battery is 9V and there are 12 servos branched at the Arduino UNO.
