Initially, the chip on the arduino is very hot to the touch.
Think I 'bricked' my arduino uno. I'm a newbe and I succeeded in getting my first project working ( solenoid actuated by modified Blink.pde sketch). However, I tried to use a multimeter to measure the voltage on my breadboard and I managed to power off my PC. My test leads must have transmitted the stored current from the solenoid.
QuoteInitially, the chip on the arduino is very hot to the touch.Which chip? The ATmega?If your ATmega is removable, remove it. If the PC recognizes a Uno is attached, then the board and 8u2 (serial to usb) is working.If anything on the board is hot (or even warm) to the touch, when connected to usb and no other hardware is connected, then that chip is likely dead.
