Code

Use the following Arduino code to display data from the Serial Monitor onto the 16×2 LCD Display module:

//For more Projects: www.arduinocircuit.com

#include <Wire.h>
#include <LiquidCrystal_I2C.h>

LiquidCrystal_I2C lcd(0x27, 16, 2); // Set the LCD address to 0x27 for a 16x2 display

void setup() {
  Serial.begin(9600);
  lcd.init();      // Initialize the LCD
  lcd.backlight(); // Turn on the backlight
  lcd.clear();     // Clear the LCD screen
  lcd.setCursor(0, 0);
  lcd.print("Serial Monitor");
  lcd.setCursor(0, 1);
  lcd.print("to LCD Display");
  delay(2000);     // Display the startup message for 2 seconds
  lcd.clear();     // Clear the LCD screen
}

void loop() {
  while (Serial.available() > 0) {
    lcd.clear(); // Clear the LCD screen
    lcd.setCursor(0, 0);
    lcd.print("Received: ");
    char receivedChar = Serial.read(); // Read a character from Serial Monitor
    lcd.setCursor(0, 1);
    lcd.print(receivedChar); // Display the received character on the LCD
  }
}

Applications

The Serial Monitor to LCD Display project has various applications, including:

1. Real-Time Data Display: Showcase real-time information or sensor data on the LCD.
2. Debugging Tool: Display debugging messages or variable values during the development process.
3. Information Display: Present important messages or instructions to users using the LCD.
4. Interactive Displays: Create interactive projects where user input from the Serial Monitor is reflected on the LCD.

Conclusion

By following this tutorial, you’ve learned how to display data from the Serial Monitor onto a 16×2 LCD Display module using an Arduino Nano. We discussed the necessary components, provided clear connections, and offered a functional Arduino code for the project. Now you have the knowledge to create your own versatile display system that bridges the gap between your Arduino projects and the Serial Monitor, adding a new level of interactivity and functionality.
