I'd really appreciate some advice on a project that I'm right in the middle of. I hope I've posted in the right section - I've searched the rest o the forum but I still don't really understand how to tackle my problem.
I'm trying to get a coin-mech (the type used in arcade machines) to work with the arduino. it is a single coin type that allows the pulse to be set manually.
The wiring harness for the mech is as follows:
grey line: counter (+/-) red line: DC +12V White line: Coin Signal Black Line GND grey Line: counter (+/-)
The spec sheet for the mech states that the timer Switch, for synchronising the system has three options: 100ms 50ms 30ms
OK.. from what I understand i would need to use the White Line to ascertain when a correct coin has been inserted - counting the pulses, I believe..
Firstly, I haven't been able to work this out. Secondly, I think I blew one of the pins by putting the line straight into my arduino - how do I avoid this?
Many thanks for any advice!
