QlTimeMachine is one of my very first projects in C++ (please, be kind). It is supposed to used on a Wemos D1 Mini (or other microcontroller) with the LED-matrix MAX7219 8x32 and a few buttons.
Microcontroller GND -> LED-matrix GND
Microcontroller 5V -> LED-matrix VCC
Microcontroller D5 -> LED-matrix CLK
Microcontroller D7 -> LED-matrix DIN
Microcontroller D8 -> LED-matrix CS
Microcontroller D1 -> Pushbutton (other pin to GND)
Microcontroller D3 -> Switch (other pin to GND)
See instructions on platformio.
