Step 3Connect the Arduino
iImage Information

Slide some heat shrink tubing over the cable then break off a row of 6 right angle headers and solder the 6 LED wires to them. Once soldered cover the wires with hot glue for insulation then add and shrink some additional tubing to cover. This will provide a good solid connecter for plugging into the Arduino. Be careful when shrinking over the hot glue as it will remelt if it gets too hot. Repeat the same process for the ground wire with a single header then slide the heat shrink tubing up the cable shrink everything together.
Since the Arduino project enclosure doesn't really allow for much to be added above and beyond the Ethernet shield we need to make a few modifications to it. We need to remove the 6 female header block from the analog pins and also clip off one of the GND pins. Once completed plug in the Control Center cable and stack the Ethernet shield on top.
