What is a 4 digit segment display?

A seven-segment display (SSD), or seven-segment indicator, is a form of an electronic display device for displaying decimal numerals that is an alternative to the more complex dot matrix displays.

Seven-segment displays are widely used in digital clocks, electronic meters, basic calculators, and other electronic devices that display numerical information.

Material Required:

Material Quantity

Arduino Uno 1

4-digit segment display 1

Jumper cables 4

Pin of 4-digit segment display:

1. GND.

2. VCC.

3. DIO.

4. CLK.

Circuit Diagram:

Connect the 4 Digit Segment Display with Arduino as follows:

1. GND pin of 4 Digit Segment Display to GND of Arduino

2. VCC pin of 4 Digit Segment Display to 5V of Arduino

3. DIO pin of 4 Digit Segment Display to digital pin 2 of Arduino

4. CLK pin of 4 Digit Segment Display to digital pin 3 of Arduino

Library Required

You have to download the library for Arduino of 4 Digit Segment Display

The link is given below: https://github.com/avishorp/TM1637

Tested Programming Code:

#include <TM1637Display.h>

//Set the CLK pin connection to the display

const int CLK = 3;

//Set the DIO pin connection to the display

const int DIO = 2;

int numCounter = 0;

//set up the 4-Digit Display.

TM1637Display display (CLK, DIO);

void setup()

{

//set the diplay to maximum brightness

display.setBrightness(0x0a);

}

void loop()

{ //Iterate numCounter

for(numCounter = 0; numCounter < 1000; numCounter++)

{ //Display the numCounter value;

display.showNumberDec(numCounter);

delay(1000);

}

}

Precautions:

1. Double-check the connections before powering on the circuit.

2. Don’t use loose jumper cables.

3. Check whether the proper board is selected from Arduino IDE.

4. Ensure proper placement of 4-digit segment display for correct working.

Conclusion:

Once your sketch is running, you have to see the 4-digit segment display. It starts display.
