Backend part of a complete dispenser program for a custom kegerator. Frontend can be found here.
API interface to use a frontend that can send HTTP requests that trigger interface with GPIO pins.

Log on to getBeer_WiFi_configuration hotspot and choose the correct wifi. Make sure you choose the same WiFi as your frontend.
Once the backend is logged on, go to your router and reserve the IP 192.168.10.99 (you may need to change this to 192.168.0.99 or another IP of your choosing in the frontend, depending on your router). Alternatively you can reserve whatever IP the SensorBackend received, and update the frontend accordingly.
