Virtual IoT Lab DEI

Instructions

Objective:

Learn how to interface and display text messages on a 16x2 LCD display using Arduino and the LiquidCrystal library.

Steps to Perform:

Click "Start Simulation" to power up the Arduino circuit
The LCD display will initialize and show "Virtual Lab" on the first line
Messages will automatically scroll on the second line every 2 seconds
Four different messages will be displayed in sequence
The sequence will loop continuously until you stop the simulation

Key Concepts:

LCD 16x2: Display module with 16 columns and 2 rows for text
LiquidCrystal Library: Arduino library for easy LCD control
Pin Configuration: Uses pins 2-5, 11, 12 for LCD communication
lcd.begin(): Initializes LCD with specified dimensions (16, 2)
lcd.setCursor(): Sets cursor position (column, row) for text display
lcd.print(): Displays text at current cursor position
lcd.clear(): Clears all text from the display

Arduino Code - main.ino

            #include <LiquidCrystal.h>
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

String message[] ={
"This is a ",
  "Sample Program",
  "to Interface",
  "LCD 16x2 Module."
};

void setup(){
lcd.begin(16,2);
}

void loop(){
  for(int i=0;i<4;i++){
  lcd.clear();
    lcd.setCursor(0, 0);
    lcd.print("Virtual Lab");
    lcd.setCursor(0, 1);
    lcd.print(message[i]);
    delay(2000);
  }
}
