Stap 2: Bevestig de Arduino LCD schild aan de arduino
De Arduino LCD Shield hechten aan de arduino en aansluiting op uw PC worden geprogrammeerd.
Hieronder is mijn Arduino Sketch, merkte ik dat de opmaak rommelt met de code een beetje, ik heb wat meer informatie beschikbaar met betrekking tot deze build kunt u ook hier de code bekijken.
