ATtiny85 - terza parte

PASSO 7
Caricare lo sketch rammmentadosi che non tutte le istruzioni di Arduino Uno vengono accettate, della piedinatura del chip e della non eccessiva memoria dell'ATtiny.
Non confondere il pin del chip con la porta.

Sketch di prova:blink

     /* Piedinatura di ATtiny85
         PB0 (0) = pin 5 tested
         PB1 (1) = pin 6 tested
         PB2 (2) = pin 7 tested
         PB3 (3) = pin 2 tested
         PB4 (4) = pin 3 tested (mio led)
         PB5 (5) = pin 1 non riuscito.Forse perchè è anche RESET?
