Changes very specific to my cabinet, allowing coin mech to be ready when a game starts
Change gpio to pin 27 to avoid clash with CRT rotate

Could you add a little decsription of the intended use of this addition for the public? I add this then to the wiki. |

I don't really know if this will be useful for anyone else or work in the same way for different credit boards, so I'm not sure if it is suitable for you to include as-is ... but here's a description and will leave it up to you: Activate electronic coin acceptor when game startsBy default If you have an electronic coin mech then it will always be active and accepting coins even when no game is running. If you have suitable hardware, it is possible to use the 'machine ready' handshake so that the coin mech rejects coins until a game is started from the regamebox menu. If you have a lamp in your coin mech it should also light up when a game starts. To achieve this we send a signal from a GPIO pin (using pin 27), to a 5v relay switch (like this one: https://cpc.farnell.com/velleman-kit/vma406/5v-relay-module-for-arduino/dp/SC14425). The relay switch will be connected to the credit board to switch the 12v machine ready signal on/off. |

Such a function can be used in several ways. I think its a good idea to collect ideas how to use such a feature. I used the same kind of relay for turning CRT, you for turning on and off coin mech. I`m sure there is more to do with that. |
