So I got my first Arduino, an Uno, today. Not realizing it would probably power itself through USB, I connected it to a power supply too. After a couple minutes of messing with the board (it worked fine) it stopped.
I looked at the cables and realized I connected the wrong one - with 24V. Unplugged it, but not fast enough, I think, because now the board doesn't work. When I power it up (through USB) the microcontroller will become very hot almost immediatly. The green ON LED works, but nothing else. The computer recognizes the device, but the programs won't upload, error appears:
avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51
What do you think, is it fried?
EDIT: oops, I posted in a wrong section, sorry. Looks like I fail at everything today.
