Each button has two LEDs above it. I may have to replace them but it simplifies my design. They do require rewiring.
Now I need to get the front face repainted. Need to figure out how to re-label the buttons.

Got my Arduino today... been writing code for 3 days and decided I need an actual Arduino to run it on ;-)
So I have managed to get the AVR talking to my PC so I do know this is possible, at least for the AVR.
More details to come soon.

And the project now has a name... It will be called a ZMZ-1... which stands for... wait for it, Zappy McZapface, in honour of Boaty McBoatface

 Testing serial connection. Spent all weekend coding. Still a long long way to go |

 Will need washers for this... The box is so thick that the shield is too deep |

So you have it up and working, then?

So, you are using a Mega! That puppy has enough I/O to switch on/off 5 rooms of equipment!  Coding tip: learn to use and create class libraries if you aren't already. |

I have very little up and running. Mostly concept testing. I write embedded software for a living so this has been fun so far. I've been waffling between class libraries for ease of maintenance and code sharing and much more low level for speed. It may end up using a hybrid of both. I have managed to read the amp and control the tv over serial from my mac. This week I want the Arduino itself to do that.

i think the 9pinD caps should be on the inside of the case and the screws the only thing on the outside

i think the 9pinD caps should be on the inside of the case and the screws the only thing on the outside That is indeed how they should be. But I need washers to do that since the screws are smaller than the existing holes. Should be updating it this weekend. Right now I am working on the control panel and the UX port |

I cannot find any documentation on the trigger voltage, and current... in, nor out. Anyone able to help? The out would be from my XMC-1, and the in would be to my XPA-1Ls

The out would be from my XMC-1, and the in would be to my XPA-1Ls For Chuck's circuit he used a Zener diode to bring to 12v trigger from the XMC down to 5v for the trigger input signal to the Arduino Uno. 12v works as trigger inputs to the amplifiers which is taken from the 12v supply to the Uno and fed to the relays. |

An engineer friend of mine was suggesting a voltage divider with resistors. I wonder which approach would be better
