Step 1: Assembly
Wire the neopixel by connecting the ground from the NeoPixel ring to ground on the arduino and +5vdc from the NeoPixel ring to +5vdc on the arduino. The neopixel ring can be very bright so if you want the option to dim the instensity of the ring, simply connect a potentiometer in line with the +5vdc. Connect data input from the NeoPixel ring to digital pin 6 on the arduino. Use hot glue on the bottom of the arduino, at all the wired connections for support and to attach the NeoPixel ring to your laptop stand.
Step 2: Upload the Code
Download the Adafruit Neopixel library zip file below. To install the library, open the arduino ide. Go to Sketch->Include Library->Add ZIP Library... and select the library you downloaded. Now upload the "simple" sketch from File->Examples->Adafruit_NeoPixel-master->simple to your arduino. That's it!
