Refer t # Pinout (DUE) -The Arduino DUE has 3.3v logic whereas the Pop'n Music cabinet lamps use 12V. Therefore I'm using mosfet transistors to do level shifting (the parts I used were three ULN2003APG chips). You can also buy pre-made level shifters such as this one https://www.tindie.com/products/ddebeer/12-channel-level-shifter-and-buffer/ (you'd need two of them since there are 18 lamps to control for a Pop'n cabinet). +The Arduino DUE has 3.3v logic whereas the Pop'n Music cabinet outputs (lamps, coin blocker, coin counter) use 12V. + +Therefore I'm using transistors to do level shifting (the parts I used were three ULN2003APG or TBD62003APG chips).
