Jukebox
A music jukebox: select the song and play it!
Two buttons, one buzzer and a seven segments led with three resistors and a few wires to get a music jukebox capable of playing 16 songs.
Once the code is uploaded one button is used to cycle on the available songs while the other starts the playing.
Look up the code to see how I get past the SRAM limitations using PROGMEM to store the songs.
I developed the SevenSegments library used to drive the led display, still work in progress.
