I fried my uno board it seems because I can't upload anything to it now.
I was running 4 continuous rotation servos off the 5V pin of the board.
I am a complete beginner and just want to clarify two things.
1: Should I have a separate power supply for each servo or just a single separate supply for all 4 ?
2: My beginner kit came with a 9V battery pack containing 6AA batteries. It plugs into the side of the uno. Is this supply fine to run the uno?
Thanks for your help.
