Arduino Tutorial - Servo with External power supply

Servo, can be powered by another power source without Arduino power. Only thing important here is that all the GND are connected to each other.

Hardware Required

Hardware Required :

  • Arduino or Genuino Board
  • Servo Motor
  • Battery for Servo (I used for my servo; 4pcs (1.5V) batteries.)
  • Mini Breadboard
  • Wires

Like this you can add as many servo motors as you want.

***Important! If you will use high voltage battery and you want give power to arduino with same power source, you need to put a 7805 voltage regulator in, and make a parallel circuit for that too.
