Arduino LCD 16X2 Keypad Shield

Arduino LCD 16X2 Keypad Shield

This is a 16x2 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
Pin Connections
Pin Function
Analog 0 Buttons (select, up, right, down and left)
Digital 4 DB4, Digital 5 DB5, Digital 6 DB6, Digital 7 DB7, Digital 8 RS (Data or Signal Display Selection),Digital 9 Enable

Note: Do not use pin Digital 10 when this board is plugged in (see here for more details)
The board is a little bigger than an Arduino UNO (measuring 8cm x 6cm). This can be seen in the images.
