Providing more power
September 29, 2008
Ok, so i have my Arduino, 3 x servos and an ultrasonic range finder. Running all these at once from the 5v that the arduino provides is not supplying enough current (i think). I can run at maximum any two of these components from the 5v.
So i guess my solution is that i need to supply the servo's with their own separate power source.
If i hook up some AA batteries to the + wires of the servos connect the gnd to the gnd and the PWM wire to the arduino, will this work? How have other people dealt with this problem?
I'm not really concerned with power efficiency at the moment, i just want to get it working.
Any help is appreciated :-)
