The Smuggie: Tweet straight from your Snuggie

Step 11Hook the Smuggie up to our Arduino.

Simply connect one lead of the soft switch to the power port on the Arduino, and the other lead to Pin 12 with a 10k resistor in between.

Here is what our Smuggie circuit will look like.

In your picture it looks like you have pin 12 shorted to ground. The switch won't be doing anything. You'll need to have a larger value resistor between pin 12 and ground than between pin 12 and the switch.
If Arduino's have built in pull ups, you could just enable the pull up on pin 12 and connect the switch to ground on one side and use a 1-10k resistor (pull ups are usually between 10-50k, not sure about on atmega.) with no second connection.
