i am having the biggest problem with the arduino coding for the automatic dog feeder i am making. i have the arduino uno, protoshield, servo, PBNO, and a 9v power supply. and i am using the coding that the original person used. But at the beginning it say:
int btn = 0;
int test = 5;
and it says there is an error in these 3 lines of the coding saying there was an error because setup was void, PLEASE HELP. i cannot figure it out for my life!
