Step 1: Gather the Materials
A Soldering Iron
A soldering iron can be purchased at quite a few places. For electronic work you'll want a lower wattage iron, try checking out radioshack.
Three Breadboard Wires
Breadboard wires have pins on each end, which make it very simple to plug them into breadboards and pin headers. I purchased mine from adafruit.com, it is a very reliable site, which also sells everything else needed to complete this project.
Here are the breadboard wires that i bought www.adafruit.com/index.php
This is very self explanatory. You need this for clipping and stripping the wires.
This is for joining your wires together. Check adafruit.com or radioshack.
These can be found on many hobby stores and websites. I actually purchased mine from amazoncom.
The heatshrink wrap is for insulating your bare solder joints. this can be purchased from radioshack or any other electronic parts supplier.
