   LM34 Temperature Sensor Sketch
   
   This sample sketch is for LM34 IC
   Temperature Sensor, it can display the
   degrees in Fahrenheit and Celcius.
   
  STEP 1: Construct the circuit of GizDuino Temperature sensor.
  STEP 2: Connect the USB Cable to your computer.
  STEP 3: Open the Arduino IDE.
  STEP 4: Open the Temperature sensor (LM34) Sample code from GizDuino Starter kit code.
  STEP 5: Then, click Upload.
  
  This sample code is simply read the Sensor output.
