   Blinking 8 LEDs
   
   STEP 1: Construct the circuit of GizDuino Blinking 8 LEDs.
   STEP 2: Connect the USB Cable to your computer.
   STEP 3: Open the Arduino IDE.
   STEP 4: Open the BLINKING 8 LEDS Sample code from GizDuino Starter kit code.
   STEP 5: Then, click Upload.
   
   This sample code turns ON the LEDs in 1 second and turn OFF
   in 1 second. It is a simple and easiest way using more pins
   for blinking LEDs.
