This repository contains the source code of what the Arduino is running: reading temperature and power from the coffee machine and serving it over the wire to whomever listens.
This project has a few dependencies that you are required to install to be able to compile your code, these can all be downloaded through the built-in library downloader in the Arduino IDE.
This code has only been tested on an Arduino Uno, so no guarantees for any other
kind of board. To use it simply open the arduino.ino file in the Arduino IDE,
configure it to read/write to the correct USB port and compile and push it.
If you want to read data you need to open the TTY display and send a 1 which
the Arduino will receive and return the latest reading from its sensors.
Anything else is simply ignored.
