Could I have fried something on my Arduino Uno, either firmware or hardware? It has been driving a pair of servos on pins 10 and 11 24/7 for a few years (activating them for a few seconds every eight hours), but now that I've added a SainSmart relay on pin 0 I cannot get the servos to work anymore, even on other pins, even after removing the relay and uploading backup software. I noticed that when I uploaded the new software, the relay chattered and its led flickered. I realize that pin 0 has something to do with communications, so I moved the relay to pin 10 and moved the servos to other pins too (not pin 0). Now the relay works fine on pin 10 but the servos still do not work. I also tried new servos.
Do I just buy a new Arduino, or is this fixable? I'm going to try some printf's to verify that I'm actually attempting to drive the servos, that something hasn't messed more with my code than I thought.
