Hello,

Glad you enjoyed the project! To upload the firmware, you can do so with dfu-programmer over USB, or with an AVR ISP such as ArduinoISP.

You will need to run the Makefile to build a *.hex file, which you could then upload to your atmega32u4 using one of the above methods.

Hope this helps!
