Anche io POV con Attiny

POV: Persistence of Vision
è quel fenomeno per cui, se vi sventolate una mano davanti alla faccia, vedete un sacco di dita...
lo state facendo adesso vero?
sfruttando questo fenomeno possiamo per esempio riprodurre dei caratteri grafici componendoli "una colonna alla volta" e spostandoci poi di un'altra colonna...

 

Chi fa questa cosa? Questo arnese qui:

Da sinistra: le batterie (3V sono sufficienti) l'interruttore, l'attiny 85 e i 5 led collegati.

che post di merda che sto scrivendo.

La scritta "Ciao belli!" manca la lettera C, c'era un piccolo bug risolto...

Questo è lo schema, sotto aggiungo il codice. ciao, arrangiatevi.
