LCD Keypad Arduino Uno

LCD Keypad Arduino Uno

The LCD Keypad  Arduino Uno 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 > “select”, “up”, “right”, “down” 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.

The LCD-Keypad Shield 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!

This LCD Keypad Shield use total of 6-pins to control the LCD display which is pin-4, 5, 6, 7, 8, 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 such as shown in figure below.
