hi, hope someone can help me, as I am a total newbie. I am building a chainlink counter for my boat. I am using a proximity sensor and I would like the arduino to tell me how many meters of chain has been rolled out through the windlass. So the display should state 5, 10, 15, 20, 25, 30, 35 or 40 …

Code for counter

Yes, I realized after my input, that I have to connect the signal cable, also to the GND of the Mega.... but thanks very much....
