Features
What the UI can do.
Quantity input
The user can choose between different glass sizes. The pumps run according to the set quantity.
Python control
The interface is directly linked to the GPIO control of the Raspberry Pi — no detour, no middleware.
Touch-optimised
All controls are generously sized and designed for use with a 7-inch touch display.
Technology
Developed with Python.
The entire interface is based on Python and was optimised specifically for the Raspberry Pi. The direct integration of the GPIO pins allows pump commands to be sent from the UI without delay.
