This is the beerbox project, TODO: add better readme ;-)
# The Beerbox Project
The Beerbox Project features a digital counter for drunken beer, or other drinks.
To identify a user the Beerbox can ether use an RFID tag or a fingerprint. Once a user is identified it books the credits of the selected drink to him/her. The selected dirnk can be changed via the push of a button.
TODO: build intructions & hardware documentation
