Stap 3: De code
Ik kreeg deze code van iemand anders. Ik weet niet remenber zijn naam of waar ik het kreeg zo kredieten aan de anonimous kerel. Hoewel ik sommige grote veranderingen in de code dus ik alleen de basis van de code van deze kerel gebruikte.
Implementeren van de juiste bibliotheek in uw map ' Bibliotheek ' in de kaart van de arduino voordat u Kopieer de code en beginnen met het uploaden. U kunt dit als volgt vinden: C: Windows--> programmabestanden (x86)--> Arduino.
Anyway, hier is de code (maar u beter het bestand downloaden):
