/*
  Takes the Analog value from a potentiometer and writes it on the screen in percentage
  The circuit:
  * LCD RS pin to digital pin 12
  * LCD Enable pin to digital pin 11
  * LCD D4 pin to digital pin 5
  * LCD D5 pin to digital pin 4
  * LCD D6 pin to digital pin 3
  * LCD D7 pin to digital pin 2
  * LCD VEE pin to ground

  * 10K resistor:
  * ends to +5V and ground
  * wiper to Analog pin 2
