Mein erstes eigenes Netduino Projekt. Mit 6 LEDs bilde ich die Funktion eines Würfels nach.

Über den Onboard-Switch wird eine neue Runde eingeleitet. Es werden 2x nacheinander alle LEDs angeschalten um eine kleine Animation zu machen und danach wird das Ergebnis über die LEDs angezeigt. Zusätzlich wird im Debugger ausgegeben was der “Würfel gerade macht”.

Für Vorschläge was man besser / anders machen kann, bin ich natürlich immer offen.
