Stap 5: De code
Codering voor mij is een pijn!
Ik shearched op het web werken arduino schets.
Veel van hen niet werken, maar ik vind deze kerel op youtube:
Hij heeft een goede baan en een goed werkende code geven over zijn codebender:
Ik gekookt zijn code met meer patronen zoals: candy cane, theater stijl of regenboog wielen
Dit is mijn werkende code:
