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
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.
Step 5: If I Was Helpful
First of all, I would like to thank you for reading this guide ! I hope it helps you.
