Knight Rider Circuit

This time its not a big project. Its just a simple circuit that uses a arduino uno, 9 Red LEDs , a Resistor, few jumpers and a breadboard to make the LEDs act like the LED panel in the michael's car.

Here the Things Needed for this project.

1. 9 Red LEDs.
2. A 220 Ohm Resistor.
3. Mini Bread board.
4. Jumpers.
5. Arduino Uno with the cable.

First of all fix the LEDs and the resistor as shown.

Remember to start from the pins above 1. You can use them but it may occur some problems while uploading to the board. Make sure to carefully observe the circuit diagram.

I am not going to explain far about the code. Simply Its programmed to Turn one led on then wait about 40 milliseconds and then trun on the other one. And It will go again and again.

Heres the code.

int pin2 = 2;
int pin3 = 3;
int pin4 = 4;
int pin5 = 5;
int pin6 = 6;
int pin7 = 7;
int pin8 = 8;
int pin9 = 9;
int pin10 = 10;
int timer = 40;
void setup(){
  pinMode(pin2, OUTPUT);
  pinMode(pin3, OUTPUT);
  pinMode(pin4, OUTPUT);
  pinMode(pin5, OUTPUT);
  pinMode(pin6, OUTPUT);
  pinMode(pin7, OUTPUT);
  pinMode(pin8, OUTPUT);
  pinMode(pin9, OUTPUT);
  pinMode(pin10, 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(pin8, HIGH);
   delay(timer);
   digitalWrite(pin8, LOW);
   delay(timer);
   digitalWrite(pin9, HIGH);
   delay(timer);
   digitalWrite(pin9, LOW);
   delay(timer);
   
   digitalWrite(pin10, HIGH);
   delay(timer);
   digitalWrite(pin10, LOW);
   delay(timer);
    
   digitalWrite(pin10, HIGH);
   delay(timer);
   digitalWrite(pin10, LOW);
   delay(timer);
   
    digitalWrite(pin9, HIGH);
   delay(timer);
   digitalWrite(pin9, LOW);
   delay(timer);
   
   digitalWrite(pin8, HIGH);
   delay(timer);
   digitalWrite(pin8, 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);
}
