KNIGHT RIDER EFFECT USING ARDUINO

                               

•  Lets see how to switch on set of LEDS sequentially.

Using Fritzing software,I have developed breadboard structure and schematic for easy understanding.Let check these things below.

Here is the following code written on microcontroller of arduino board.

int pin2 = 2;
int pin3 = 3;
int pin4 = 4;
int pin5 = 5;
int pin6 = 6;
int pin7 = 7;
int timer = 100;

void setup(){
  pinMode(pin2, OUTPUT);
  pinMode(pin3, OUTPUT);
  pinMode(pin4, OUTPUT);
  pinMode(pin5, OUTPUT);
  pinMode(pin6, OUTPUT);
  pinMode(pin7, OUTPUT);
}

void loop() {
   digitalWrite(pin2, HIGH);
   delay(timer);
   digitalWrite(pin2, LOW);
   delay(timer);

   digitalWrite(pin3, HIGH);
   delay(timer);
   digitalWrite(pin3, LOW);
   delay(timer);

   digitalWrite(pin4, HIGH);
   delay(timer);
   digitalWrite(pin4, LOW);
   delay(timer);

   digitalWrite(pin5, HIGH);
   delay(timer);
   digitalWrite(pin5, LOW);
   delay(timer);

   digitalWrite(pin6, HIGH);
   delay(timer);
   digitalWrite(pin6, LOW);
   delay(timer);

   digitalWrite(pin7, HIGH);
   delay(timer);
   digitalWrite(pin7, LOW);
   delay(timer);

   digitalWrite(pin6, HIGH);
   delay(timer);
   digitalWrite(pin6, LOW);
   delay(timer);

   digitalWrite(pin5, HIGH);
   delay(timer);
   digitalWrite(pin5, LOW);
   delay(timer);

   digitalWrite(pin4, HIGH);
   delay(timer);
   digitalWrite(pin4, LOW);
   delay(timer);

   digitalWrite(pin3, HIGH);
   delay(timer);
   digitalWrite(pin3, LOW);
   delay(timer);
}
