The KA06 LCD shield from Velleman is designed to add display functionality to projects using the Arduino Uno microcontroller project board. The easy to assemble kit features a 20-character, 4-line negative blue LCD module with a white LED backlight. Additional features include a contrast adjust trimmer, backlight On/Off switch, reset button and three user-configurable pushbuttons (3x digital input / 1x analog input). This project is perfect for visualising measurements, parameters, data, settings, messages, etc.
Sample programs to run the KA06 on an Arduino Uno are available here: Sample code for KA06
