DESCRIPTION:
Arduino LCD 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 followin
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
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
Digital 10
Backlit Control
HIGH = Backlight on
LOW = Backlight off
Use PWM signal to control brightness

Installing library:
Download and unzipped the library folder, and place it to the Arduino libraries directory. Once the library is correctly inst
should look like:
arduino-0010/hardware/libraries/LCD4Bit_mod
arduino-0010/hardware/libraries/LCD4Bit_mod/LCD4Bit_mod.cpp
arduino-0010/hardware/libraries/LCD4Bit_mod/LCD4Bit_mod.h
arduino-0010/hardware/libraries/LCD4Bit_mod/keywords.txt
arduino-0010/hardware/libraries/LCD4Bit_mod/examples
arduino-0010/hardware/libraries/LCD4Bit_mod/readme.txt
Open the example from file -> Examples -> LDC4Bit_mod -> LCD4Bit_modExample, as shown in the screenshot below.
