Board Arduino UNO R3
Hi at all,
I've used the board for some week but this evening when i've connected the board i doesn't see the device in Device Manager List and when i Plug and unPlug the USB i can't ear the "device connected" sound.
I've try with two different PC but nothing!!
The UNO have the L13 Led ON and green power Led On.
If I press Reset Button L13 blink and after 3 sec. go ON again.
I 'think i must to Reset the 16U2 , right?
how can i reset it?
