Hi guys,

I've tried integrating interrupts for and sleep from this link here

into my code and it didn't work as intended so i uncommented it out and ran my normal code and now my normal code seems to be locking up or hanging? I added Serial.prints all around my functions and it seems to run about 7-9 times before it "hangs". When i close and reopen the serial monitor, the code resets and it restarts to run 7-9 times  again before hanging. Does anyone know the cause of this?

Things I've tried:

- Re-uploading blank sketch -> working as expected
- Using sleep_disable() and detachInterrupt -> didn't seem to have done anything
- Implementing a basic timer and Serial.print -> working as expected
- Hard resetting the nano -> resets as expected
- Checked ADC if it was turned on/off -> it is on as expected

Things i did notice:
- Before i uploaded the sketch with the interrupts, the LED on the Nano itself was Green+Red and my sketch was working as expected
- After the sketch was uploaded with interrupts, the red LED is not lighting up

Any advice or help would be beneficial! Many Thanks
