Grazie della guida Guglielmo
Questo sono le impostazioni dell' IDE :
Scheda : ATtyny 25/45/85
Processore ATtyny 85
Programmatore : Arduino as ISP
per verifica questi sono i collegamenti Arduino Nano e l' AT :
Piedino 7 SCK: D13
Piedino 6 MISO: D12
Piedino 5 MOSI: D11
Piedino 1 RST: RST
Piedino 8 : 5v
Piedino 4 : GND
condensatore 10uF tra RST e GND
Con le impostazioni di cui sopra questo è l' errore che riscontro
