Scrolling Text on LCD with Arduino

Scrolling Text on LCD with Arduino

• You candownload the complete simulation here by clicking on the button below.

Arduino Source Code

• Just download .rar file, extract it and enjoy the complete simulation.

Interfacing 16×2 LCD to Arduino uno

Designed Circuit in Proteus ISIS

• .Now just copy and paste the given source code in the Arduino software

#include<LiquidCrystal.h> //Library for LCD
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);// LCD pins at which it is attached to the Arduino

void setup() //method used to run the source for the one time onlys
{
  lcd.begin(16, 2);//LCD order i.e. 16 columns & 2 rows
  lcd.print("The Engineering Projects ");//prints on LCD
  lcd.setCursor(0,1);//setting cursor on LCD
  lcd.print("www.TheEngineeringProjects.com");//prints on LCD
  delay(1000);//delay of 1 sec
}
void loop() //method to run the source code repeatedly 
{
 lcd.noDisplay();//turn off the display of LCD
 delay(250);//delay to 0.25 seconds
 lcd.display();//turning on the LCD display
 delay(250); //delay of 0.25 seconds again
}

• Now compile the source code and get hex file from it as shown in the figure below.

• Copy this address as shown in the figure above.
• Double click on Arduino UNO in proteus, a new window will be opend as shown in the figure below.
• Paste that address in the file menu as encircled in the figure below.

• Run the proteus simulation from the Arduino software from the upper left corner of the software.
• If everything goes perfect you will see the output as shown in the figure below.

• Copy and paste the source given below in your Arduino software.

#include <LiquidCrystal.h>//Library for LCD
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);//LCD pins at which it is attached to the Arudino

void setup()//method used to run the code for once 
{
  lcd.begin(16, 2);//LCD order
  lcd.print("The Engineering Projects ");//prints on LCD
  lcd.setCursor(0,1);//Setting the cursor on LCD
  lcd.print("www.TheEngineeringProjects.com");//prints on LCD
  delay(1000);//delay of 1 second
}

void loop() //used to run the code repeatedly
{
 for(int PositionCount=0;PositionCount<13; PositionCount++)//loop for scrolling the LCD text
  {
    lcd.scrollDisplayLeft();//builtin command to scroll left the text
    delay(150);// delay of 150 msec
    }

   for(int PositionCount=0; PositionCount<29; PositionCount++)
   {
    lcd.scrollDisplayRight(); //builtin command to scroll right the text
    delay(150);//delay of 150 msec
    }
   for(int PositionCount=0; PositionCount<16; PositionCount++)//loop for scrolling the text
   {
    lcd.scrollDisplayLeft();//builtin command to scroll the text left again
    delay(150);//delay of 150 msec
    }
}

• Compile the code given above.
• Obtain the hex file as I told above in the figure.
• And open it in your proteus as I described above.
• Run the simulation like the I have previously done.
• You will be able to see the scrolling text on LCD as shown in the figure below.

• That all from this article to show Scrolling Text on LCD using Arduino.
• Was it difficult? I don't think so :)
