Robin2:
What happens when you run that version?What happens when bring the un-commented lines back into use?
...R
I wrote in post #14 - It works like before, just without the need to reach a coinsValue >= 1 (keypad works even if no coins were put through the acceptor).
When I bring the lines back to use - it also doesn't need coins - keypadInput(); is outside IF loop. But now LCD says "Skambink!" when 1€ is reached.
Now I cannot rut the coin acceptor anymore since my 12V 2A transformer seem to be blown up. Will have universal power source in the lab tomorrow.
