How to use digit 7-segment LED display with Arduino

In this post, we’ll discover how to use digit 7-segment LED display with Arduino. This screen is used to display numbers, letters, and symbols. It’s used in electronics projects, such as Arduino projects, to display measurements, words, symbols, and more…
To use a display with an Arduino correctly, simply follow the steps below.

Electronic components that we need:

• One 7-segment display
• 2 resistors (220 Ohm)
• Electrical wires
• Arduino UNO
• Breadboard

Arduino Programming Code:

    int A = 7;
    int B = 6;
    int C = 4;
    int D = 3;
    int E = 2;
    int F = 8;
    int G = 9;
    byte num0 = 0x3F;
    byte num1 = 0x6;
    byte num2 = 0x5B;
    byte num3 = 0x4F;
    byte num4 = 0x66;
    byte num5 = 0x6D;
    byte num6 = 0x7C;
    byte num7 = 0x7;
    byte num8 = 0x7F;
    byte num9 = 0x6F;

    void on(byte num){
    int result = bitRead(num, 0);
    if (result == 1)
    {digitalWrite(A, HIGH);}
    else
    {digitalWrite(A, LOW);}
    result = bitRead( num, 1);
    if (result == 1)
    {digitalWrite(B, HIGH);}
    else
    {digitalWrite(B, LOW);}
    result = bitRead( num, 2);
    if (result == 1)
    {digitalWrite(C, HIGH);}
    else
    {digitalWrite(C, LOW);}
    result = bitRead( num, 3);
    if (result == 1)
    {digitalWrite(D, HIGH);}
    else
    {digitalWrite(D, LOW);}
    result = bitRead( num, 4);
    if (result == 1)
    {digitalWrite(E, HIGH);}
    else
    {digitalWrite(E, LOW);}

    result = bitRead( num, 5);
    if (result == 1)
    {digitalWrite(F, HIGH);}
    else
    {digitalWrite(F, LOW);}

    result = bitRead( num, 6);
    if (result == 1)
    {digitalWrite(G, HIGH);}
    else
    {digitalWrite(G, LOW);}
    }
    void setup() {
      // put your setup code here, to run once:
    pinMode(A, OUTPUT);
    pinMode(B, OUTPUT);
    pinMode(C, OUTPUT);
    pinMode(D, OUTPUT);
    pinMode(E, OUTPUT);
    pinMode(F, OUTPUT);
    pinMode(G, OUTPUT);
    pinMode(10,OUTPUT);
    }
    void loop() {
      // put your main code here, to run repeatedly:
    on(num0);
    delay(1000);
    on(num1);
    delay(1000);
    on(num2);
    delay(1000);
    on(num3);
    delay(1000);
    on(num4);
    delay(1000);
    on(num5);
    delay(1000);
    on(num6);
    delay(1000);
    on(num7);
    delay(1000);
    on(num8);
    delay(1000);
    on(num9);
    delay(1000);
    }
