I'm considering using an Arduino Uno for a final year (secondary/high school) project. I need to control 6 servo motors, with each of them only needing to move a few degrees (no more than 5).
Forgot to connect back to ground pin in this rough diagram
The examiner will only be turning my device on for literally 2 or 3 minutes (if even). Is it viable to use an arrangement of AA or AAA batteries to power these servos externally for this short period of time or will I have to use a wall power supply (provided I supply the Uno separately)?
Any help is appreciated.
