The code for a piggy bank and coin sorter I made using a Raspberry Pi, an Arduino, Lego Mindstorms NXT, a coin acceptor, Adafruit's LCD Plate, and a fingerprint sensor. It counts, sorts, and stores coins.

  • The Arduino is connected to the Raspberry Pi via a USB hub; it communicates with the fingerprint sensor and detects what kind of coin is inserted.

  • A Python script outputs information to the LCD display and stores data in a text file.

The code was written by Alex Strandberg and is licensed under the MIT License, check LICENSE for more information

Much of the Arduino code was taken from:
