Seven Segment Display

The Seven Segment Display project demonstrates how to interface a common cathode seven-segment display with an Arduino Nano to display numbers from 0 to 9. Seven-segment displays are commonly used for numerical representation in digital devices such as digital clocks, timers, and counters.

Circuit Setup

Connect Seven Segment Display to Arduino Nano:

Connect segment A to pin 2 on the Arduino Nano.

Connect segment B to pin 3 on the Arduino Nano.

Connect segment C to pin 4 on the Arduino Nano.

Connect segment D to pin 5 on the Arduino Nano.

Connect segment E to pin 6 on the Arduino Nano.

Connect segment F to pin 7 on the Arduino Nano.

Connect segment G to pin 8 on the Arduino Nano.

Connect the common cathode pin of the display to GND.

Instructions

1.Circuit Setup:

Wire the seven segment display to the Arduino Nano as described in the circuit setup section.

2.Code Upload:

Open the Arduino IDE and paste the provided code.

Upload the code to the Arduino Nano.

3.Testing:

Once the code is uploaded, observe the seven segment display.

The display will cycle through numbers from 0 to 9 repeatedly

Applications

Digital Counters: Use seven segment displays to show counts in various applications such as timers and counters.

Digital Clocks: Implement seven segment displays to display time in hours and minutes.

Measurement Devices: Utilize seven segment displays to show measurements such as temperature and humidity.

Notes

Ensure the correct pin mapping between the Arduino Nano and the seven segment display.

Adjust the delay value in the code to control the speed at which the numbers are displayed.

Experiment with additional segments to display characters or symbols beyond numeric digits.
