Interactive MP3 Donations Box
Posted: 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 http://cefn.com/blog/files/MoreMusicDonationsBox.pdf
You can see some more about the construction in this album...
