Hey guys,
Just wondering if i powered the arduino with a 9V Lithium Battery (input)
then from the arduino's 5V and ground, connect a 1.5V AA Battery
then from 1.5V AA connect a Servo Motor, would that mean the Servo would be given 6.5V?
I made a image representation to show what i mean better-
Also did i connect the positive and negative wires to the AA battery properly?
Thanks a bunch guys
You connected the 1.5V battery ACROSS the 5V. Not good.
Connect +5 to the - side of the battery and the + side of the battery to the power pin of the servo.
Use a separate power supply for servos and other motors - don't share with the Arduino's logic supply.
A servo is basically a motor. Motors generate current spikes at turn-on of several amps (overloads the onboard regulator and crow-bars the supply rail reseting the Arduino), and can produce inductive voltage spikes capable of trashing semiconductors if you are unlucky (perhaps this is less a problem with a servo than a bare motor).
