I was connecting LEDs to the digital output pins on my Arduino UNO, and I wanted to test to make sure they were hooked up properly. I connected 7 volts to each led, which was also connected directly to the digital ports on my arduino. The Arduino now won't load with code, and the blinking orange LED labeled L doesn't light up ever. When I try to download code, the compiler returns this: avrdude: stk500_getsync(): not in sync: resp=0x00.
One of the surface mount resistors or capacitors (too small to tell) heats up a lot whenever I turn on the arduino.
Did I fry my Arduino, or is there a method for fixing this issue?
