Product Description

The LCD and Keypad Shield gives you a handy 16-character by 2-line display, 5 buttons and a controllable backlight, plug it straight in on top of your Arduino board or other project shields. The display is set behind the shield for a low profile fitment and nice look and we've included panel mounting screw holes in the corners.


It's great when you want to build a stand-alone project with its own user interface that doesn't require a computer attached to send commands to your Arduino.

Works perfectly in 4-bit mode with the "LiquidCrystal" library included with the Arduino IDE, allowing you to control the LCD with a total of just 6 digital I/O lines. We've deliberately picked D4-D9 so that it doesn't interfere with pins required by other popular products such as the Ethernet Shield and EtherTen, so you can stack this on top of other shields to give you a local display.

There are 5 buttons, and when press any combination of these buttons, each will give an unique value. That means that it is able to tell 32 different possibility.


The LCD backlight is connected to a potentiometer can be controlled for on/off, brightness.


Difference between v1 and v2:

In v1, the 5 buttons can only be pressed one at a time. In v2, any combination of the buttons can be pressed at the same time, this lead to 32 different combinations!
