Hallo, ich bin absoluter Anfänger, habe aber voriges Jahr ein Arduino-Baukasten geschenkt bekommen. Nach ersten Versuchen bin ich nun hier. Mein Ziel ist es, die bisherige Steuerung eines Reifeschrankes durch einen Arduino mit Touch-TFT zu ersetzen. Ein paar Zeilen habe ich schon geschrieben, Temperatur und Feuchte kann ich messen. Nun würde ich gern die Sollwerte mit Buttons verändern wollen. Genau das aber, bekomme ich nicht hin. Habe mehrere Stunden gefummelt und probiert. Ich raffe es einfach nicht. Vielleicht kann mir hier jemand behilflich sein. Der TFT ist einer von LCDWIKI, scheinbar funktionieren auch nur diese Bibliotheken. Hier der Code.
