Schritt 2: Zuordnen der Arduino Arduino LCD-Schirm
Der Arduino beimessen Sie Arduino LCD Schirm, und schließen Sie ihn an Ihren PC programmiert werden.
Unten ist mein Arduino-Sketch, bemerkte ich, dass die Formatierung mit dem Code ein wenig verwirrt, habe ich einige weitere Informationen finden Sie im Zusammenhang mit diesem Build können Sie auch hier den Code anzeigen.
