Following a bit of a think about how i want this to go...

I will be moving the 'heavy lifting' off to a webserver of some kind, the main user interface will be accessible via WiFi where drinks can be selected etc.

This allows for multiple people to choose at once, its not as tactile as pressing clicky buttons (something i quite enjoy) but it has many benefits.

To this end, the teensy 3.1 has been replaced with a Nano, the SD card has been removed and code radically changed to reflect that.

Its now a great deal simpler, particularly as I've decided to remove scrolling menus (it was a lot of faff and never completely worked properly)

All of the 'pouring' functionality can be triggered from the CLI now, including naming of the reagents, on that note, I MAY get some little oled displays to show the reagent names next to the feeds, this could be useful when considering the expansion board (16 more reagents)

It is also possible to manually dispense things and prime the feeds, drain, clean and alter the LED settings from the on board UI.

I will make a little demo vid of the functionality at some point, but for now, here is a pic of it all lit up :-)
