Arduino 7-Segment Display Counter

This project demonstrates how to drive a 7-segment display using an Arduino. The display counts from 0 to 9, with each digit displayed for one second. Each segment (A to G) of the display is controlled using individual digital output pins on the Arduino.

Features

• Counts from 0 to 9 with a 1-second delay between numbers.
• Each digit is displayed using corresponding segment control.
• Easily modifiable for custom sequences or applications.
• Suitable for beginners learning to control LEDs or segments with Arduino.

Hardware Requirements

• Arduino Uno (or compatible board)
• 7-Segment Display (Common Cathode)
• 8 Resistors (220Ω or 330Ω recommended)
• Jumper wires
• Breadboard

Pin Configuration

Each segment is connected to an Arduino digital pin:

Segment	Arduino Pin
A	13
B	12
C	11
D	10
E	9
F	8
G	7
H (Decimal Point or Extra LED)	6

Note: Segment H is optional and is not used in this project.

Installation

1. Clone this repository:

   git clone https://github.com/Asish-SGeorge/arduino-7segment-counter.git

2. Open the .ino file in the Arduino IDE.

3. Connect your hardware as per the pin configuration.

4. Upload the code to your Arduino board.

Usage

Once uploaded, the 7-segment display will count from 0 to 9, displaying each digit for one second before moving to the next.

Code Structure

• Each digit (0–9) is implemented as a separate function (zero(), one(), etc.).
• setup() initializes all segment pins as outputs.
• loop() cycles through all the digit functions in sequence with a 1-second delay.
