K9 - Control Panel

This weekend I'm changing the button signals to I2C signals. I was disapointed to find that the Raspberry pi could only be a master so will not respond to I2C signal. It will only request data from slaves.

Progress is slow but getting there.
Nano support and some wiring
Arduino Nano One to control the LED's in the switches. Arduino Nano 2 to detect button pushes and send via the I2C bus. Arduino Nano 3 & 4 to control the LED matrix in 2 red displays. Only One LED matrix fitted and half wired.
Power and signals to the control panel through the 9 pin D-type connector.
