Interactive MP3 Donations Box

Post by cefn » Tue Jan 30, 2018 8:22 pm

This was a commission by More Music who wanted an interactive donations box in their hallway. We proposed an interactive, coin-driven MP3 player and were lucky enough to win the commission.


The device is based on an ESP8266 connected to a DFPlayer Mini MP3 Breakout board and MCP23017 for GPIO expansion (to add multiple infrared reflectance detectors for the coin slots).

The original proposal can be found at

You can see some more about the construction in this album...

The MP3 Player was driven by this library...

The GPIO expander was driven by this library...
