Stap 3: Software
1e van alle downloaden en installeren ADAFRUIT Neopixel Library
Hier is mijn code met enkele grote beschrijvingen (Ik voegde ook de schets-bestand). Ik didn´t commentaar elke stap, omdat ik denk dat het isn´t nodig.
Uploaden van de schets op uw ATTiny85 en veel plezier met je nieuwe speeltje
Ideeën voor "persoonlijkheid" functie + misschien code-voorbeelden zijn zeer welkom :-)
Als er vragen, voel je vrij om vragen.
Ik hoop dat u genoten van mijn korte instructable en de kleine reis in de wereld van ATTINYs.
