MULTIPLE LED BLINKS

MULTIPLE LED BLINKS

INTRODUCTION:

we can glow multiple LED with the help of arduino.due to it's schedular library we can do so.

now let's see how things happend......................................

HARDWARE REQUIRED:

• Arduino (uno)
• breadboard
• five LED
• jumper wire

THE CIRCUIT:

here we connect  all the positive side LED pin to the arduino (digital pin) we started from 13 no. pin afterthat 12,11,10 and 9  by using jumper wire and breadboard. now connect  a negetive pin of LED with arduino using jumper wire.and same way by using jumper wire conncet all the negetive pin with ground.

CODE:

void setup(){

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

pinMode(13,OUTPUT);

pinMode(12,OUTPUT);

pinMode(11,OUTPUT);

pinMode(10,OUTPUT);

pinMode(9,OUTPUT);

}

void loop() {

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

digitalWrite(13,HIGH);

digitalWrite(12,HIGH);

digitalWrite(11,HIGH);

digitalWrite(10,HIGH);

digitalWrite(9,HIGH);

delay(5000);

digitalWrite(13,HIGH);

digitalWrite(12,LOW);

digitalWrite(11,HIGH);

digitalWrite(10,LOW);

digitalWrite(9,HIGH);

delay(1000);

digitalWrite(13,LOW);

digitalWrite(12,HIGH);

digitalWrite(11,LOW);

digitalWrite(10,HIGH);

digitalWrite(9,LOW);

delay(1000);

digitalWrite(13,HIGH);

digitalWrite(12,HIGH);

digitalWrite(11,HIGH); 

digitalWrite(10,LOW);

digitalWrite(9,LOW);

delay(1000);

digitalWrite(13,LOW);

digitalWrite(12,LOW);

digitalWrite(11,LOW);

digitalWrite(10,HIGH);

digitalWrite(9,HIGH);

delay(1000);

digitalWrite(13,HIGH);

digitalWrite(12,HIGH);

digitalWrite(11,LOW);

digitalWrite(10,LOW);

digitalWrite(9,LOW);

delay(1000);

digitalWrite(13,LOW);

digitalWrite(12,LOW);

digitalWrite(11,HIGH);

digitalWrite(10,HIGH);

digitalWrite(9,HIGH);

}

NOTE:HERE WE CAN USE RESISTOR  (220 ohm) ALSO  GENERALLY RESISTOR IS USED FOR TO PROTRCT OUR LED WE CONNECT OUR RESISTOR WITH THE POSITIVE PIN OF LED.
