Hi Guys,
I have google about this one, but i don't find any related topics about this issue.
Actually I have buy new one arduino uno R3 yesterday.
When I connect it to my PC, The "L" led is not blinking, i think it should blinking
I have try to connect it to my mac and windows its not detected as arduino or usbmodem but detected as Atmega.
Any suggest to solve this issue?
Is it possible my arduino is broken?
