Description

Cattune PCB

This project is an one octave piano with a 555 timer and a learning feature where, instead of playing freely a LED will light up showing which note should be pressed, inspired in some musical keyboards that have this kind of feature. The project includes a Attiny 85 that the user can load with three led lighting sequences and three buttons that can be used to start reproducing these sequences. Once the sequence starts, the user can start to play along to learn the song.
