Für die Ansteuerung des LCD wird `rpi-pico-i2c-lcd` von _T-622_ ([Github](https://github.com/t-622/rpi-pico-i2c-lcd)) verwendet, das wiederum auf `python_lcd` von _dhylands_ ([Github](https://github.com/dhylands/python_lcd)) basiert. Letzteres steht unter der MIT-Lizenz. `rpi-pico-i2c-lcd` ist ohne Lizenzangabe. Die entspechenden Dateien liegen der Einfachheit halber im `lib` Unterverzeichnis.
### Installation
Am einfachsten ist es, mittels [Thonny](https://thonny.org/) die Datei `main.py` sowie den `lib`-Ordner ins Hauptverzichnis des Picos zu kopieren. Auf dem Pico muss natürlich MicroPython installiert sein. Fertig.

Das Gerät wird über ein microUSB-Kabel mit einem 5V Netzteil, wie man es zum Aufladen von Smartphones verwendet, verbunden. Der Raspberry Pi Pico benötigt sehr wenig Strom, es genügt daher ein "schwaches" Netzteil. Der Euro-Stromstecker kommt an die Steckdose. Damit ist (über ein Relais) das andere Stromkabel, das mit einer Euro-Buchse versehen ist, verbunden. An diese Buchse wiederum kommt die Heizmatte. Das letzte Kabel – in meinem Fall das hellgraue – ist der Temperaturfühler. Dieses muss über eine Bohrung o. ä. in die Gärbox eingeführt werden, so dass eine Temperaturerfassung des Innenraums möglich ist.
Mit den blauen Tasten stellt man die gewünschte Temperatur ein. Rot schaltet die Heizungssteuerung ein/aus. Ein ">H<" zeigt an, ob gerade geheizt wird.
