Title: Proper counter wiring?
Post by: iscariot on June 12, 2009, 10:55:42 am

I've got a coin counter I want to wire. How do I wire to both coin slots at once?

You will either need some diodes or an OR chip, I believe.

Good luck.

I believe it can be done with just diodes but you run the risk of running too much current through your encoder.  The safest way is with diodes and transistors.  I have set this up before (I had relays powering the counter but that is overkill...the circuit is basically the same though).  If no-one else posts a schematic, I can draw one up this weekend.
