In the ground next to the toroidal transformer you can see an Arduino Nano, where the two 1-Wire temperature sensors (18ds20) and the Display go. The temperature sensors can be seen on the second picture from above.
The Display has an RGB backlight - when the amplifier is cold, the display is blue, when it is at the right temperature, the display is red.


An externally hosted image should be here but it was not working when we last tested it.

The trigger input is handled by the Arduino as well I guess ?
