Project Title

Arithmetic progression display using Arduino with lcd display

Description

Arithmetic progression means a sequence of numbers where the difference between two consecutive numbers is constant.This constant value is called the common difference.The project is mainly designed for students,beginners and electronics hobbyists to understand the relationship between mathematics,programming and embedded systems.It demonstrates how an arduino Uno can perform mathematical calculations and display the output on an LCD Screen or serial monitor.

The LCD screen is used to show the sequence terms clearly.The ardunio controls the display and updates the values after a fixed delay.Some advanced versions allow users to enter custom starting numbers and common differences using buttons.This project is very useful in educational environments because it provides practical understanding of arithmetic progression concepts.Students can visually observe how sequences are generated mathematically and electronically.

Components Used

Arduino Uno
16*2 LCD display
Jumper wires

Arduino Code


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


// Initialize LCD (Address 0x27, 16 columns, 2 rows)
LiquidCrystal_I2C lcd(0x27, 16, 2);

int a = 2;       // First term
int d = 4;       // Common difference
int n = 9;      // Number of terms to display

void setup() {
  lcd.init();
  lcd.backlight();
  
  lcd.setCursor(0, 0);
  lcd.print("AP Sequence:");
  delay(1500);
}

void loop() {
  for (int i = 0; i

What is Arithmetic progression?
Arithmetic progression is a sequence of numbers where the difference between consecutive terms is always constant.This constant value is called the “common difference”.

Working principle

The working priniciple of the project is simple.The arduino calculates arithmetic progression terms using mathematical formulas programmed in the code.These values are then sent to the LCD display.The arduino continuously updates the LCD screen after a short delay,making the sequence visible to the user.
