simple 7 segment display driver using arduino uno

simple 7 segment display driver using arduino uno
                  Here is a simple code for arduino for driving a 7 segment display.

                          code

            int timer = 500;           // The higher the number, the slower the timing.

void setup() {
  // use a for loop to initialize each pin as an output:
  for (int thisPin = 0; thisPin < 14; thisPin++)  {
    pinMode(thisPin, OUTPUT);    
  }
}

void loop() {
  // loop from the lowest pin to the highest:
  for (int thisPin = 0; thisPin < 14; thisPin++) {
    // turn the pin on:
    digitalWrite(thisPin, HIGH);
    delay(timer);                
    // turn the pin off:
    digitalWrite(thisPin, LOW);
 delay(timer);  
  }

  // loop from the highest pin to the lowest:
  for (int thisPin = 7; thisPin >= 2; thisPin--) {
    // turn the pin on:
    digitalWrite(thisPin, HIGH);
    delay(timer);
    // turn the pin off:
    digitalWrite(thisPin, LOW);
  }
}

Here this code uses for loop for the selection of o/p pins and also for the state of each pin
steps

• connect the ground and vcc of the display to the grnd and the +5v pin of arduino respectively.
• connect the a,b,c,d,e,f, pin of ur display to the output pins(1-13) of arduino. ( u can connect it in any order as u like)
• connect ur arduino to ur lap or pc
• coppy the lnk above and paste it to the arduino Ide
• upload the programme
