16X2 LCD Display

This is one of the most popular display device used. This is a 16x2 (16 Characters on 2 lines) LCD with Black font and Yellow Backlight.

There are many readily available libraries for interfacing it with Arduino, Raspberry Pi or other Development Boards and Micro-Controllers/Processors.This can be operated in either 8 Bit or 4 Bit mode of operation. In the 4 Bit mode, it'll only require 6 Control pins from the Microcontroller.

Pin Mapping:

Ground VCC (+3.3 to +5V) Contrast adjustment (VO) Register Select (RS). RS=0: Command, RS=1: Data Read/Write (R/W). R/W=0: Write, R/W=1: Read Clock (Enable). Falling edge triggered Bit 0 (Not used in 4-bit operation) Bit 1 (Not used in 4-bit operation) Bit 2 (Not used in 4-bit operation) Bit 3 (Not used in 4-bit operation) Bit 4 Bit 5 Bit 6 Bit 7 Backlight Anode (+) Backlight Cathode (-)
