Description

This Arduino-based "Coffeemaker Payment System" is ideal for small office and institutes! It uses the service port (serial port) of the coffeemaker, so you won't lose your guarantee! In theory, it will work with many houshold coffeemakers, but the commands in the code may have to be changed. It works quite nice with a Jura Impressa S95. For registering, charging and deleting cards as well as updating the price list I made an app with the MIT app inventor. Like this project? Please leave a comment! Both, Arduino code and Android app are still in experimental status! Use at your own risk! Instead of the app, any bluetooth terminal program can be used, if on a smartphone or notebook. Hardware: RFID reader RDM630, HC-05 bluetooth dongle, a buzzer, a 16x2 LCD, Arduino Uno, housing, f/m jumper wires and/or sensor cable. https://github.com/oliverk71 Please flattr me! Update: changed the code and use the hardware serial to communicate with the coffeemaker now. Will upload it these days, but not today. Merry x-mas ;)
