Tutorial: How to use LCM1602 LCD IIC/I2C Module for Arduino

The LCM1602 LCD IIC/I2C module is a useful component for displaying information on a liquid crystal display screen. This tutorial will guide you through the installation and configuration of the module with Arduino.

What you need

• Arduino Uno/Nano
• LCM1602 LCD IIC/I2C Module (SKU: ARD00178)
• USB cable to connect Arduino to the computer
• Arduino IDE Software

Steps

1. Connect the LCD module to an I2C port of Arduino using the appropriate cables.
2. Open the Arduino IDE and install the LiquidCrystal_I2C library from the library manager.
3. Upload the following sketch to your Arduino to test the module’s functionality.
4. Check that the I2C settings are correct by consulting the module’s datasheet.
5. Modify the sketch to display the desired data on the LCD screen.
6. Test additional features such as text scrolling and display backlighting.
7. Try integrating the module into a more complex project, such as a weather station.
8. Resolve any I2C communication errors by following the instructions in the datasheet.

Example code

LiquidCrystal_I2C lcd(0x27,16,2); // impostare l'indirizzo e dimensioni del display
lcd.begin();
lcd.print("Benvenuto!");

Mini project

Build a simple weather station that displays temperature and humidity on an LCD screen.

Common mistakes
