Coin Meter Will Not Increment
<< < (2/3) > >>
yotsuya:
Cut the end off a USB cord (the device end, not the end that goes in your computer). Find the red and a black wire. Connect red wires together. Plug the cord in. Then touch the black end of the USB cord to the black end of the coin meter. This should trigger a pulse and flip the meter up one number. Do it a couple of times and see if the numbers move.

Kinda like this... (without the black plug i added)

Ah you guys are excellent! I was able to get the meter to successfully increment this way (despite my usb cable attempting to fool me with it's white. blue, yellow and green wires... :banghead:)

So that leaves an error in my wiring, a potential board problem, or some other thing that I must be overlooking... Perhaps Arkanoid does not work like most arcade boards?
PL1:
You may want to read this KLOV thread on the subject.

Per Ken Layton,

The thread mentions two kinds of meters -- internal diode models and external diode models.

Related pic from the thread showing an external diode model.
(for your 5v meter, substitute a 5v connection instead of the 12v connection shown)

Thanks for the link. I did read the thread, however my wiring matches what is described in that thread. Still not sure what it is wrong. I have a +5 volt line going to the red terminal of the internal diode 5 volt coin meter, and the coin meter wire from the Arkanoid board (non jamma) going to the black lead of the coin meter.  I will have to test it out more later today.
