Arduino Uno defective?


I've just started using my starter kit. Currently i'm on project 02.
The problem is when i push the button, the Uno seems to completely "poweroff", the led on it are off.
There's no problem with the code as i've experimented and everything works, only this is not working.

Thanks a lot in advance, i'm gonna try to change I/O pins to see what it does.

(mod edit)

You're using a diode to ground; when pushing the button, you short Vcc to GND via the diode.

Use a 10k resistor instead.

Ah thanks a lot!

I feel so stupid. :smiley:

If that is a cloth of some description you are sitting your Arduino on then please find a better surface.

Some types of cloth carry a lot of static and could kill some boards.
