This is my code for a darkroom timer using:
- IoT Relay (power switch)
- 8x8 x4 LED Matrix
- USB Numpad
Install everything, then some more stuff, and then the rest.
* Start key capture (to input time via number keys) + Add a tenth of a second - Remove a tenth of a second / "Focus" - Turn the enlarger on ENTER "Print" - Enlarger on, timer countdown, auto enlarger off
