Please excuse my ignorance, but I'm a noob at best when it comes to voltage/wiring/etc, but I'm working on an idea I have and I'm trying to figure out how to trip the COIN pin on a JAMMA board to add a token to the machine.
I've wired a JAMMA fingerboard to act as a middleman between the cabinet and the arcade board and have wired an extra wire to pin 16 that goes to a pin an Arduino board. Then, I would use the arduino to send send a signal and trip the pin to add a token.
In theory, this makes sense in my head, but so far it's not working and my first thought is that maybe I don't have the right voltage to trip the pin on the JAMMA harness, or if an Arduino can do it at all?
Thoughts?
