This example demonstrates how to display "Hello World" on a 16x2 LCD using the I2C interface. The I2C module simplifies wiring and reduces the number of pins required.
Code Example
#include <Wire.h>#include <LiquidCrystal_I2C.h>// Initialize the LCD with I2C address 0x27, 16 columns, and 2 rowsLiquidCrystal_I2C lcd(0x27, 16, 2);void setup() {lcd.init(); // Initialize the LCDlcd.backlight(); // Turn on the backlightlcd.setCursor(0, 0); // Set cursor to column 0, row 0lcd.print("Hello World"); // Print "Hello World"}void loop() {// No actions in the loop for this example}Copied!âś•CopyKey Considerations
Wiring: Connect the SDA and SCL pins of the I2C module to the corresponding pins on your Arduino (e.g., A4 and A5 for Arduino Uno).
Library: Ensure you have installed the LiquidCrystal_I2C library via the Arduino Library Manager.
I2C Address: The default I2C address is 0x27. If your LCD uses a different address, adjust it in the code.
