Do you need an easy to use interface for your LCD screen? The LCD Button Shield just might be your answer! Moving through menus and making selections straight from one stand-alone shield attached to your Arduino is a great way to cut down on your tower of shields.
The LCD Button Shield consists of a 16x2, black character, green backlight LCD with a keypad consisting of 5 keys — select, up, right, down and left. To save the digital I/O pins, the keypad interface uses only one ADC channel. The key value is read through a 5 stage voltage divider.
Note: Headers are included but not soldered.

Note: The analog values in the library and datasheet seem not to be correct since Linksprite changed the resistor network slightly. A customer has sent us the below measured values for both versions of the shield:
Version V2.1
============
UP : Normal = 930 -> Trigger = >=916 / <949
Down : Normal = 902 -> Trigger = >=879 / <916
Left : Normal = 855 -> Trigger = >=835 / <879
Right : Normal = 814 -> Trigger = >=714 / <835
Select : Normal = 613 -> Trigger = >=513 / <714
Version V2
==========
Up : Normal = 628 -> Trigger = >=605 / <641
Down : Normal = 581 -> Trigger >=546 / <605
Left : Normal = 511 -> Trigger = >=487 / <546
Right : Normal = 463 -> Trigger = >=422 / <487
Select : Normal = 381 -> Trigger = >=340 / <422
We thank R.S. for sharing his findings with us.
