Develop an interfacing circuit and a sketch to increment count on 7-Segment based on switch press. Count goes from 00 to 99.

Here i am using online IDE Tinkercad . If you don't know what is tinkercad then refer my blog HERE or else you can use offline IDE also.

Code:-

void setup()

{

  for (int i = 0; i <= 13; i++)

    pinMode(i, OUTPUT); //Set all pins from 0 to 13 as OUTPUT

}

//The line below is the array containing all the binary numbers for the digits on a SSD from 0 to 9

const int number[11] = {0b1000000, 0b1111001, 0b0100100, 0b0110000, 0b0011001, 0b0010010, 0b0000010, 0b1111000, 0b0000000, 0b0010000};

 

void loop()

{

  for (int tens = 0; tens < 10; tens++)

 

  {

    display_tens(tens);

  }

}

 

void display_tens(const int tens)

{

  int pin1, a, ones;    

  //pin1 is just used to deal with pins of the 1st SSD which desplays the tens digit

 

  for (pin1 = 0, a = 0; pin1 < 7; pin1++, a++)

  {

    digitalWrite(pin1, bitRead(number[tens], a));

  }

  for (ones = 0; ones < 10; ones++)

  {

    display_ones(ones);

    delay(300);

    //I have given a delay of 300 milliseconds. You can put your own Time!!

  }

}

 

void display_ones(const int x)

{ int pin2, b;            

//pin2 is just used to deal with pins of the 2nd SSD which desplays the ones digit

 

  for (pin2 = 7, b = 0; pin2 <= 13; pin2++, b++)

  {

    digitalWrite(pin2, bitRead(number[x], b));

 

  }

 

}

Output:-
