Description: Do you need an easy to use interface for your LCD screen? The LCD Button Shield V2 attaches to your Arduino to provide a 16x2, black character, green 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.
The LCD Button Shield V2 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. Version 2 of 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!

Note: Headers are included with this shield but not soldered on.

This is my first shield to go along with my first Arduino board (SparkFun RedBoard), and it was a good choice. For those somewhat new to electronics and Arduino, this shield is quite easy to understand. The sample code is a different story. Keep in mind you will need to solder on the headers to attach this shield to an Arduino.
All of the buttons have a different value resistor tied to ground and analog pin A0, which should give you a different value if you analogRead() pin A0. This keeps the analog pin usage to a minimum, as well as allows you to push more than one button at a time (which may not be that useful with this button arrangement). You can also set the LED backlight brightness by writing via analogWrite() to pin 10 a value of 0 to 255 (this outputs a PWM signal at a duty cycle defined by your input value).
The quality of this board is pretty good, but my OCD kicked in when I saw the LCD soldered in not completely straight. The stackable headers are not useful for stacking something on top of the LCD, but are for breadboard prototyping.
The price is good, seeing that the same price only gets you a SparkFun branded display on this site. Overall, I would recommend this shield to anyone.
