Step 13: Connect LED
We now wire up the LED. We solder the LED to the ground we wired up in the last step, as well as to a wire that leads to digital 5. When the button on the shell is pushed, this LED will provide feedback to the user that that data is being off-loaded from the device. The LED will remain lit during the entire off-loading process and then turn off. Through a series of digital Writes we will enable and disable the LED.
