ProtoSnap LilyPad Development Simple Hookup Guide
Unsnapping and Tacking
I'm just going to go ahead and jump on in, since you guys warmed up on part 1! If you're here, you should have your code working adequately, so go ahead and snip the pieces of the ProtoSnap apart. I'll go ahead and take them all off at once. We'll get them all secured to the project quickly, so you shouldn't have to worry about losing parts. Use your wire cutters to snip the connections between the boards. Do this carefully -- you don't want to cut into or snap apart any of the hole you'll use for sewing later.
Make sure that you also snip off any extra sharp bits after you've taken these pieces apart
Once all of your parts are snipped apart and cleaned up nice and smooth, it's time to start sewing! Start with your non-conductive thread. We're going to go ahead and secure the parts to your project so that everything is already attached and oriented the way you need it to be. This will make it easier to connect things with your conductive traces, because it will be easy to see both the starting and ending point. Grab your Arduino simple board first. Turn it so that the "9" pin is facing where you want the buzzer to go. In my case, that's towards the tip of the ray gun. It won't take a lot of stitches- you certainly don't have to tack down every sewing hole on the board. I just chose two across from each other and sewed those down.
Next, let's tack down the buzzer. You'll want the positive pin pointed back towards pin 9 on the Arduino, and the negative pin pointed forwards, towards the tip of the gun.
Finally, get the LEDs tacked down. You want them in a straight row, with the positive sides up and the negative sides down
