Arduino IDE Code:

const unsigned int DELAY_DISPLAY = 500;

const byte PINS[] = {4, 5, 10, 9, 8, 3, 2, 11};  // pins from left to right: A, B, C, D, E, F, G, DotPoint

const byte BYTES_DISPLAY[] = { // list of bytes to display from top to bottom, 1 byte = 8 bits, bit froms right to left

  B00111111, // 0

  B00000110, // 1

  B01011011, // 2

  B01001111, // 3

  B01100110, // 4

  B01101101, // 5

  B01111101, // 6

  B00000111, // 7

  B01111111, // 8

  B01101111, // 9

};

void setup() {

  // put your setup code here, to run once:

  for(byte indexPin = 0; indexPin < sizeof(PINS); indexPin++) {

    pinMode(PINS[indexPin], OUTPUT); // set pins A, B, C, D, E, F, G are out put.

  }

}

void writeDigit(byte digit) {

  for(byte indexPin = 0; indexPin < sizeof(PINS); indexPin++) { // indexPin (from left to right in array) = indexBit (from right to left in calculator)

    bool isOn = digit & (1 << indexPin); // get bit at indexPin; from right to left; value 0 = LED off = LOW; value 1 = LED on = HIGH

    digitalWrite(PINS[indexPin], isOn); // write out put pins (A, B, C, D, E, F, G, DotPoint) on or off

  }

}

void loop() {

  // put your main code here, to run repeatedly:

  for(byte indexNumber = 0; indexNumber < sizeof(BYTES_DISPLAY); indexNumber++) {  // each display for single digit

    writeDigit(BYTES_DISPLAY[indexNumber]);    

    delay(DELAY_DISPLAY);

  }

}
