Hello, I am trying to power the arduino braccio robotic arm without plugging its adapter into the wall. I tried powering the shield that sits on top of the arduino with a 9V battery similar to how you would power the arduino base, but the red error led lights up whenever the shield is powered on. I'm guessing this is because 9 volts is too much voltage for the shield, but I'm not sure how else to power the arm without plugging the adapter into the wall. Would a 5V battery work better for this situation? Any help would be appreciated.
Some more information: the power supply that comes with the braccio is 5V, 5A and I have 2 SR 311 and 4 SR 431 servos hooked up to the shield.
