This project is an artistic Christmas PCB developed for the Julialabs PCB Chanllange 2021.

This PCB uses an Arduino Nano as a microcontoler and has three buttons, which allow the user to choose one of three songs available in the source code: deck the halls, jingle bells and silent night. The LEDs in the PCB will light up according to the note played in each song, what wil create a nice effect. You can see the protoboard prototype clicking here. I used arduino uno for the prototype because it was the available microcontoler at the moment.

The songs used in this project were created with Sonic Pi, which made it easier to transform them into the arrays needed for the arduino program. You can check both the Sonic Pi version of the songs as the final code on the project's Github repository, which is in portuguese.

Since this is my first PCB project, I opted to make the project using only PTH components so the soldering process is easier.
