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.
- Arduino Nano
- Common Cathode Seven Segment Display
- Jumper Wires
- 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.
-
Circuit Setup:
- Wire the seven segment display to the Arduino Nano as described in the circuit setup section.
-
Code Upload:
- Open the Arduino IDE and paste the provided code.
- Upload the code to the Arduino Nano.
-
Testing:
- Once the code is uploaded, observe the seven segment display.
- The display will cycle through numbers from 0 to 9 repeatedly.
- 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.
- 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.
