Hi. I want to power a Dagu Qadbot without sources, only batteries, but don't know the best way to Do it. It uses 8 micro servo - 8g, 4~6V, and draw a current that I don't know the specific value as I didn't find a Datasheet.
So, as I'm almost sure that only Arduino will not be able to power the 8 servos, I'm thinking about 2 solutions:
1st - Use 4AA Battery to power - the Arduino i parallel with the servos. This way I'd power the servos directly and just connect the digital pin to the arduino.
