Python program freezes
I'm new to the Pi and python programming but able to solve most problems over the last 6 months. I have a program that reads voltage via an adc board and switches relays according to the voltage. This runs but after a few hours it stops with a black screen and the Pi freezes.
Trying to find what is happening I wrote a very simple loop and screen print program and again it freezes after a few hours. Any ideas? Am I missing a trick to clear working space / variables?
I didn't find the right solution from the Internet.
