Find out how to wire an LCD to an Arduino, and how to use the LiquidCrystal library through a set of useful examples. This article was revised on 2021/11/18 by Karl Söderby. The LiquidCrystal library allows you to control LCD displays that are compatible with the Hitachi HD44780 driver.

// include the library code: #include LiquidCrystal lcd(12, 11, 5, 4, 3, 2); void setup() {// set up the LCD's number of columns and rows: lcd.begin(16, 2); // set the cursor to column 3, line 0 . lcd.setCursor(3,0); // Print a message to the LCD . lcd.print("My name is"); lcd.setCursor(5, 1); lcd.print("Rachna"); } void loop() { }

Mar 9, 2019 · The example code below shows you how to display a message on the LCD. Next, I will show you how the code works and how you can use the other functions of the LiquidCrystal library. /* Basic Arduino example code for displaying text on 16x2, 20x4 etc. character LCDs.

The place where it says lcd.print("YOUR NAME") you can print your name there or change up what you want the LCD display to say. All you have to do is change the code in the brackets where it says "lcd.print".

Nov 7, 2023 · The code is written in the Arduino programming language, and it uses a library called LiquidCrystal.h to control the lcd display. We will be using an Arduino UNO board, a 16×2 LCD display, and few other electronic components.

Mar 29, 2015 · In this tutorial, I’ll explain how to set up an LCD on an Arduino and show you all the different ways you can program it. I’ll show you how to print text, scroll text, make custom characters, blink text, and position text. They’re great for any project that outputs data, and they can make your project a lot more interesting and interactive.

A liquid-crystal display (LCD) is a flat-panel display or other electronically modified optical device that uses liquid crystals and polarizers to manipulate light. Liquid crystals do not directly emit light; instead, they use a backlight or reflector to create colour or monochrome images.

This tutorial will guide you on how to write an Arduino function that displays your name on an LCD when you type it. By following the steps below, you will be able to create a simple Arduino project that showcases your name on an LCD screen.
