UNO reboots - unstable?

Hi, @gpextra
Welcome to the forum.

Can you please post a copy of your circuit, a picture of a hand drawn circuit in jpg, png?
Hand drawn and photographed is perfectly acceptable.
Please include ALL hardware, power supplies, component names and pin labels.

Can you please post your code using code tags.

Thanks.. Tom... :smiley: :+1: :coffee: :australia:
