LCD4884-Examples

LCD SHIELD WITH Nokia 5110 DISPLAY and 'Joystick' SWITCH

LCD 4884 SHIELD EXAMPLES:

Examples for the Yourduino LCD4884 Joystick Shield V3.A (Update Fix 5/4/2016 THANKS Don!)
  This LCD is available HERE
 
  NOTE: Make sure the LCD display is pushed tightly against the pc board; bend the metal tabs to hold it in place if this had not already been done. See photo.
