Each button has five connection points that are clearly marked, you need 4 of them to make them work properly. 2 pins are marked: “-” and “+” - these are for the 24v light to keep them illuminated. I used a terminal strip inside my enclosure to break out all of the voltages for easy access. But, just as easy to add a wire from the pos and gnd of the power supply. The three center pins are marked, “NC” - normally closed, “NO” - normally opened, and “C” - common. Make a connection between the “C” - common connection of the button and Arduino GND pin. (Again, I used terminal strips inside the enclosure to make wiring much easier) Make a connection between the “NO” - normally open connection and the: A2 Arduino pin (Green Button- Cycle Start/Resume) A1 Arduino pin (Yellow Button- Feed Hold) A0 Arduino pin (Red Button- Reset/Abort) Does this make sense? If not, I can try to draw something up later this evening. --- _[View the full topic](https://community.inventables.com/t/the-build-is-on/15073)._
