i was working with my arduino uno r3 on a metal plate and i think there was a short circuit. i saw a little spark. so i think i blew up my arduino.
but there are some good things, the on and L led are lighted when the usb cable is connected.
but when i try to send a program to it i get the " avrdude: stk500_getsync(): not in sync: resp=0x00 " error.
is my arduino realy blown up? is there a way i can test it? is it posible just the ic is broken so i can change it easy?
