Tutorial: How to use LCD Module 2004 (Arduino)

Learn to display text and data on an LCD display compatible with Arduino.

What you need

• LCD Module 2004
• Arduino Uno
• USB Cable
• Test Leads

Steps

1. Connect the module LCD pins to the corresponding Arduino pins.
2. Check the connection between VCC and GND.
3. Install the LiquidCrystal_I2C library in Arduino IDE.
4. Set the I2C bus in the code (check the datasheet).
5. Write the text to be displayed on the LCD console.

Example code

LiquidCrystal_I2C lcd(0x27, 2, 1, 0xF8, 0xF9, 0xFA, 0xFB, 0xFC); 

lcd.begin(20,4);
lcd.print("Benvenuto!");

Mini project
