Hi, I'm complete novice at this but I've been researching so I can create my own barn door star tracker (save on buying one for £300 !)
I plan on using an Arduino Uno in conjunction with an motor shield to drive a stepper motor.
As this needs to be a mobile item it will have to run off a battery (I have been donated a 16v 5000mah lipo).
From my research I think I can run the battery in through the external power section of the motor shield, and with some configuration, this will be also power the Uno - meaning I don't need two power supplies.
Is this right?
I appreciate your help
