Voor het vak Electrical Engineering heb ik samen met Timon Beker een digitale dobbelsteen ontwikkeld. Deze dobbelsteen heeft aan alle vier de zijde zeven NEONPIXEL LED’s. Deze adresseerbare LED’s worden aangestuurd door een door ons geprogrammeerde microcontroller. Wanneer de gebruiker met zijn of haar hand boven de dobbelsteen langs beweegt, neemt de infrarood sensor in de bovenkant van de dobbelsteen dit waar en word de dobbelsteen gerold.

Onderstaand de code die in samenwerking met Timon is geschreven.
