Insert Quarter. What a wonderful phrase, that speaks of unlimited possibility! Today, we usually just press a button on our emulators when we see those words, but how much more fun to actually drop a coin into the slot to add credits!
This project will show you how to do just that. By connecting a programmable coin acceptor to the Picade controller, you can close the contacts on your coin credit pins that would normally be driven by a button.
You could build a simple version using the Programmable 1 Coin Type acceptor, maybe to use with one type of token or coin, but here we'll use the fancy Programmable 4 Coin Type acceptor and give players two credits for a 50 cent piece, and four credits for a Sacajawea or Susan B. Anthony!
