I have uploaded the Arduino IDE code used in the artwork in GitHub. The key part of the code is the VGM player used for playing the VGM files created with the Deflemask tracker. The songs are copied in C format directly from the VGM files and it is copied at the beginning of the file. The rest of the code read the temperature from the IR thermometer and trigger the different events (songs and leds combination) when the viewer interact with the artwork.
