Step 1: Disassemble the Car

I will disassemble the current car to check the status, the existing LED system

Step 2: Replace the Old LED System LED

Replace old 3mm LED system with 5mm LED (bigger, brighter)

Step 3: Connecting the Electrical System

Connect the electrical system according to the circuit diagram in the picture

Step 4: Reassemble

Reassemble the car as it was

Step 5: Programming and Running Tests

Upload the program for the Arduino board and run it.

int ledDelay = 50;

int redPin = 5;

int bluePin = 6;

void setup() {

    pinMode(redPin, OUTPUT);

    pinMode(bluePin, OUTPUT);

}

void loop() {

    digitalWrite(redPin, HIGH); 

    delay(ledDelay);

    

    digitalWrite(redPin, LOW);

    delay(ledDelay);

    

    digitalWrite(redPin, HIGH);

    delay(ledDelay);

    

    digitalWrite(redPin, LOW);

    delay(ledDelay);

    

    digitalWrite(redPin, HIGH);

    delay(ledDelay);

    

    digitalWrite(redPin, LOW);

    delay(ledDelay);

    

    delay(100);

    

    digitalWrite(bluePin, HIGH);

    delay(ledDelay);

    

    digitalWrite(bluePin, LOW);

    delay(ledDelay);

    

    digitalWrite(bluePin, HIGH);

    delay(ledDelay);

    

    digitalWrite(bluePin, LOW);

    delay(ledDelay);

    

    digitalWrite(bluePin, HIGH);

    delay(ledDelay);

    

    digitalWrite(bluePin, LOW);

    delay(ledDelay);

}

 

The two green and red lights will flash alternately.

So it's success!
