So I have this project where I will be using 6 different servos on my Arduino board
The Servos will be connected to a breadboard, and the Arduino UNO will have a USB host shield on top of it.
These are the Servos I will be using: http://littlebirdelectronics.com.au/products/hitec-hs422-servo
I was wondering how to power these up externally As I know the UNO won’t have enough power,
Do I need to supply above 20 volts as they require 4.8-6v and I am using 6 of them?
Please point out any power issues you might find with the USB host shield.
