Introduction: Arduino : How to Use a Servo Motor With an External Power

About: Maker 101; Beginner and intermediate level Maker projects! You can find projects such as "How to" and "DIY" on programmable boards such as Arduino, ESP8266, ESP32 and Raspberry Pi on this channel. The projects…

This instructable is the written version of my "Arduino : How to Use a Servo Motor with an External Power" YouTube video that I've uploaded recently. I strongly recommend you to check it out.

Step 1: Tutorial

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.

Step 2: 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

Step 3: Circuit

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.

Step 4: Code

This example makes use of the Arduino servo library.
