Yes exactly that and I've re-written the code:

// Arduino digital pins used to light up
// corresponding segments on the LED display
#define A 2
#define B 3
#define C 4
#define D 5
#define E 6
#define F 7
#define G 8
#define DP 9

#define SENSOR 12    // Sensor connected to pin 12

int count = 0;      // current display count

const byte numbers[10] = { 
  0b1000000, 
  0b1111001, 
  0b0100100, 
  0b0110000, 
  0b0011001, 
  0b0010010,
  0b0000010, 
  0b1111000, 
  0b0000000, 
  0b0010000 
};

void setup() {
  pinMode(A, OUTPUT);
  pinMode(B, OUTPUT);
  pinMode(C, OUTPUT);
  pinMode(D, OUTPUT);
  pinMode(E, OUTPUT);
  pinMode(7, OUTPUT);
  pinMode(G, OUTPUT);
  pinMode(SENSOR, INPUT);
  lightSegments(0b1000000);
}

void loop() {
  int val = digitalRead(SENSOR);
  if (val == LOW) {
    count++;
    if (count == 10) count = 0;
    delay(500);
    lightSegments(numbers[count]);
  }
}

void lightSegments(byte number) {
  for (int i = 0; i < 7; i++) {
    int bit = bitRead(number, i);
    // segments connected to Arduino pins 2-8
    digitalWrite(i+2, bit);
  }
}

This code doesn't interfere with the 7-segment and is very reliable compared to my last attempts.

Thanks for reply :]
