Description

This is a shield designed to equip a LCD1602 and 5 push buttons into one, suitable for Arduino Uno (or Mega) form factor boards.

The LCD-Keypad Shield attaches to your Arduino board to provide a 16-character by 2-line display, white character, blue back light LCD with a keypad consisting of 5 keys, namely SELECT, UP DOWN, RIGHT and LEFT. With this shield you will be able to move through menus and make selections straight from one board attached to your Arduino without requiring a massive tower of shields or wiring tangling around.

It works perfectly in 4-bit mode with the ?LiquidCrystal? library found in the Arduino IDE, using this library will allow you to control the LCD with only 6 digital I/O lines. This shield provides you with the capability of pushing multiple buttons at once and combining the results. No longer will you be restrained to only 5 inputs, now you have the ability to make use of 32 different button combinations!

The LCD display uses total of 6-pins to control the LCD display which is digital pin 4, 5, 6, 7, 8 and 9. For LCD Data, it use pin 4, 5, 6, 7, while for the RS and Enable pin, it use pin-8 and 9. The Arduino-LCD Keypad Shield are only required to plug into the Arduino main board and there was no soldering are required.
