  This is a 16×2 LCD and Keypad shield for Arduino Uno, Diecimila, Duemilanove and Freeduino boards.

  • Blue Backlight with white words
  • uses 4 Bit Arduino LCD Library
  • Left, Right, Up, Down and Select buttons
  • Screen contrast adjustment
  • Arduino Reset button

The board uses different pins to the Arduino example sketches, so to make the display work, use the following sequence of pins when starting the library:

LiquidCrystal lcd(8,9,4,5,6,7);

The buttons are connected to only one analog input pin through resistors to give a different voltage for each button, thus saving on input/output pins. Reading the buttons is easy and example code is shown below

Package Included:
1 x 1602 LCD Board Keypad Shield Blue Backlight

The board is a little bigger than an Arduino UNO (measuring 8cm x 6cm). This can be seen in the images.
