Arduino 7-Segment Display Interface

This project demonstrates how to interface a common anode 7-segment display with an Arduino to display digits 0-9 in a loop.

Project Overview

A 7-segment display is a simple electronic display device that can display digits. In this project, we will connect a common anode 7-segment display to an Arduino and write code to display digits 0-9 sequentially.

Components

Arduino board (e.g., Arduino Uno)
Common anode 7-segment display
8 current-limiting resistors (220Ω or 330Ω)
Connecting wires
Breadboard (optional, for easier connections)

Wiring Diagram

Segment	Arduino Pin
a	2
b	3
c	4
d	5
e	6
f	7
g	8
dp	9

Connect the common anode pin of the display to the 5V pin on the Arduino.
Connect each segment (a, b, c, d, e, f, g, dp) to the corresponding digital pin on the Arduino through a current-limiting resistor.

How to Use

Hardware Setup: Connect the 7-segment display to the Arduino according to the wiring diagram above.
Code Upload: Upload the provided Arduino code to your Arduino board.
Power Up: Power the Arduino board. The 7-segment display will start showing digits 0-9 in a loop with a 1-second delay between each digit.

Important Notes

For a common anode display, setting a segment pin to LOW will turn the segment on, and setting it to HIGH will turn the segment off.
Ensure you use current-limiting resistors to protect the LEDs in the 7-segment display from excessive current.
