Danno ad arduino

-

ciao tutti ragazzi...ho fatto un danno...purtroppo durante una prova mi è capitato di fare un corto e ovviamente ho bruciato la board...ora vorrei sapere se potete consigliarmi un modo per rilevare l'entità del danno...quello che intendo è che vorrei poter capire se si è bruciato solo l' atmega e quindi basta cambiarlo oppure si è bruciato anche il regolatore di tensione e il chip per la comunicazione usb...

vi due info:

-quando attacco la scheda via usb il led on si accende (solo quello)...
-il corto mi è capitato di farlo alimentando la scheda con un alimentatore da 12v e prelevando la tensione dal morsetto vin di arduino per alimentare un rele sulla breadboard...accidentalmente ho collegato per un attimo vin gnd...

qualche idea sulle prove da fare???

se hai fatto solo quello potrebbe essere partito il diodo che sta tra la presa di alimentazione e vin, ma in questo caso arduino dovrebbe funzionare con l'alimentazione tramite usb.

ok ma hai provato se l'ide vede l'arduino e se puoi fare un upload?
ciao uwe
