LCD (Liquid Crystal Display) screen is an electronic display module and find a wide range of applications. A 16x2 LCD display is very basic module and is very commonly used in various devices and circuits. These modules are preferred over seven segments and other multi segment LED s. The reasons being: LCDs are economical; easily programmable; have no limitation of displaying special & even custom characters (unlike in seven segments), animations and so on.

1. 16 Characters x 2 Lines
2. Built-in HD44780 Equivalent LCD Controller
3. Works directly with ATMEGA, ARDUINO, PIC amd many other microcontroller/kits.
4. 4 or 8 bit data I/O interface
5. Low power consumption
6. Datasheet available on the Internet.
