So I bought the Arduino starter kit, which includes a book with 15 projects. I connected my UNO-board to my computer and it lit up like it should. I then unplugged it and wired the cables as shown in project two ( spaceship interface) (and I know that I connected everything like I should, I have triple-checked) and copied the correct code to arduino.
When I then connected my UNO-board it lit up for a moment, then it just turned off and got really hot (still is). My computer got a pop up window saying "USB Accesories Disabled, Unplug the accessory using too much power to re-enable USB devices."
I tried unplugging it and then plugging it in again, changing cable, changing computer, but nothing works. (both were mac computers)
What could be the issue?
Sorry for my bad English. :o
