Arduino I2C LCD Tutorial: Step-by-Step Guide for Beginners

Welcome to our Channel today we're diving into a simple yet powerful project connecting and using an i2c LCD with Arduino this tutorial is perfect for beginners who want to enhance their Arduino projects with a clear and easyto read [Music] display let's start with a brief introduction an i2c LCD module allows you to easily add a display to your Arduino projects it uses the i2c communication protocol which simplifies wiring and coding compared to parallel LCD modules plus it saves on precious IO pins here's what you'll need for this project an Arduino board we're using an Arduino Uno an i2c LCD module and some jumper wires first let's wire everything up the i2c LCD module typically has four pins gnd VCC SDA and connect gnd to the arduino's gnd VCC to the arduino's 5V SDA to A4 and to A5 now that we've got our Hardware set up let's move on to the software we'll be using the Liquid Crystal i2c library to install it you need to download it first I'll be posting the link to the library in the description after downloading open your Arduino IDE go to sketch include Library add zip Library locate the downloaded zip file and click open to install with the library installed it's time to write some code open a new sketch in the Arduino IDE and start by including the library at the top next we need to define the LCD address and pin configuration most I 2C LCD modules use the address 0 x27 let's write the code step by step in the setup function we initialize the LCD with 16 columns and two rows and turn on the backlight now let's move on to the loop function where we'll write the messages to the display in the loop function we clear the screen set the cursor to the first row and column and print hello after a 1-second delay we set the cursor to the First Column of the second row and print World followed by six exclamation marks this cycle repeats every 3 seconds now let's upload the code to our Arduino connect your Arduino to your computer via USB select the correct board and port in the Arduino IDE and hit the upload button once uploaded you should see Hello displayed on the first line and World on the second line of your LCD screen if you don't double check your connections and make sure you've set the correct i2c address and pin configuration you can customize your display to show different messages change the cursor position and even clear the screen let's see how we can modify our Loop function to display a dynamic message in this updated Loop function we display Arduino on the first line wait for 2 seconds then display LCD display on the second line and wait for another 2 seconds after clearing the screen we display learning on the first line wait for 1 second and then made easy on the second line waiting for 3 seconds before the loop repeats by using the LCD docar function we ensure that the screen is cleared before writing new messages the LCD set cursor function allows us to set the position where the next text will be displayed giving you control over where each message appears experiment with different messages and timings to create a display that suits your project needs and that's it you've successfully customized the display of your i2c LCD with Arduino this display can be a great addition to many projects providing clear and concise information at a glance if you found this tutorial helpful please give it a thumbs up and subscribe to our channel for more Arduino projects and tutorials thanks for watching and happy coding
