Hi! this is a simple firmware to control a pod/capsule coffee maker. It was designed to restore functionality to a machine with a blown logic board. Components needed are an arduino-compatible microcontroller (I used an Attiny45), 2 relay modules, some resistors, wires and perf-board. Code is uploaded using a usbasp programmer, but other methods are ok too. No schematics provided, but configuration of the PCB is extremely simple and only requires connections for the two buttons, one LED that was built in to the machine, thermistor with a GND resistor (usuallu 10 or 100K) and control pins for the two relays. -Barb@LILiK, 2023
