Hi, Everything was working fine, but I left my Arduino running overnight and the next day the voltage at the output pins has dropped from 5V to 3.5V, no matter what pin I choose or what sketch I run. What was it doing overnight? - it was generating a random output voltage from 0 to 5V which was go…

How is the board powered when you measure the voltage?

What is the voltage on the 5V pin?

Have you disconnected everything from the board while you are troubleshooting?
