/*
  NKC Electronics serial display - Custom Characters
 
 Demonstrates how to add custom characters on an LCD  display. 
 This sketch prints "I <heart> Arduino!" and a little dancing man
 to the LCD.
 
  The circuit:
 * LCD SCL pin to Arduino SCL pin or Analog 5
 * LCD SDA pin to Arduino SDA pin or Analog 4
 * LCD VSS pin to GND
 * LCD VDD pin to +5V
 
 Based on the original CustomCharacter example from Arduino
