At the risk of embarrassing myself here, where can I find technical documentation on the legacy BrewPi (Arduino/RaspPi) system. I would like to play around with changing a few things but have no idea where to begin as I can’t figure out how things fit together. I have tried searching but haven’t found much and what I have found are dead links.
In particular I am interested in how the whole web side of things fit together as well as the communication protocol between Arduino and Raspberry Pi.
Thanks in advance.
