Meet the Circle Electronic NOOB Series Knight Rider!

We all remember the technological car in the iconic television series Knight Rider. The most important feature of this car is that the leds on front of the car constantly turn on one by one.

For those who are new in Arduino and want to learn coding, it's time to learn how to make this animation!

Don't mess with breadboard circuits for learning Arduino and coding, just connect the cables and start coding right now!

What can you do?

-You can connect each of the 8 separate leds to the Arduino pin and make each one turn on, in turn, using the loop.

-Thanks to the buzzer on top, you can play Knight Rider theme song and learn how to make melodies using the buzzer.

-You can learn how to program 74HC593 Led driver IC. This is integrated and allows you to use 8 leds with only 3 connections. You can use this IC in other projects to use the motor or anything instead of driving a led.

Codes

8 led configuration

int leds[] = {2,3,4,5,6,7,8,9};
void setup()
{
for(int i=0; i<8; i++) {
pinMode(leds[i], OUTPUT);
}
}
void loop()
{
for(int i=0; i<7; i++) {
digitalWrite(leds[i], HIGH);
delay(100);
digitalWrite(leds[i], LOW);
}
for(int j=7; j>0; j--) {
digitalWrite(leds[j], HIGH);
delay(100);
digitalWrite(leds[j], LOW);
}
}
