Click here to download latest build (currently in development so don't expect too much)
You need to install the pymcu and python modules as described here: http://pymcu.com/Installation.html
You also need to download miniboa and put in the same folder as the coffeeserver.py.
D1 on the PYMCU is the LED indicator used showing coffee in progress. Please add 330ohm resistor in series with the LED.
D2 is a beeper element that indicates start and stop of the process.
The relay controlling the power for the coffee machine is not yet implemented, this part needs additional powersource to drive the relay.
There is a timeout of 30 secs for the process.
Next part. Get sensors for waterlevel.
