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

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.

Would it work if I powered it with 3 1,5V batteries?

[unglaublich]

thanks again for a great presentation, i understood all of it, is there any variation if i want to connect the servo motor to a l298n or vnh2sp30 to the arduino and power the servo with a battery ??? again thanks for your information, best regards

Nice tutorial. Would be interesting to also see a fritzing diagram where the arduino is connected to the same power source, for example using the mentioned 7805 voltage regulator.

Thank you for your interest. Sorry any missing information.
