About this episode

This episode covers building a 3D printed MP3 player that uses a color sensor to play different audio files based on the color of LEGO DUPLO bricks.

Build a fun and playful 3D printed MP3 player with CircuitPython and an RP2040 PropMaker Feather! It's a boombox for young makers, but with a twist: use a color sensor to detect a LEGO DUPLO brick and play a song, sound effect, or audio clip. Each colored brick plays a different audio file.
