In this video, the presenter will be demonstrating how to start using a 16×2 LCD with Arduino. The first example displays a static text message and number of seconds since Arduino reset. The next one covers modification of my Arduino ohmmeter project to display data on the 16×2 Hitachi HD44780 LCD.
Components Used: Arduino
Arduino is an open-source electronics platform based on easy-to-use hardware and software. These are able to read inputs – light on a sensor, a finger on a button, or a Twitter message – and turn it into an output – activating a motor, turning on an LED, publishing something online. Arduino designs use a variety of microprocessors and controllers. The boards are equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (shields) and other circuits. The boards feature serial communications interfaces, including Universal Serial Bus (USB) on some models, which are also used for loading programs from personal computers.
A 16×2 LCD display
A 16×2 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 LEDs. LCD (Liquid Crystal Display) is a display module commonly used in projects. The Hitachi HD44780 LCD controller is an alphanumeric dot matrix liquid crystal display (LCD) controller developed by Hitachi that was commonly used during the MCS-51 era. It was made commercially available around year 1987. The character set of the controller includes ASCII characters, Japanese Kana characters, and some symbols in two 28 character lines. Using an extension driver, the device can display up to 80 characters
Interfacing a 16×2 LCD with Arduino
It is a step by step tutorial, which will walk you through wiring the alphanumeric (text) LCD to work with Arduino Uno. You will also learn how to write a sketch (program), which lets you control the liquid-crystal display with the Arduino.
