Icon Concept (For Designer)

Ek Police Car ki chhat (roof) dikhayein jis par Light Bar lagi hai. Aadha hissa Red chamak raha hai aur aadha hissa Blue. Background mein “speed lines” hon.

What It Does (Yeh Kya Karta Hai?)

Aapne dekha hoga ke Police ki gaari ki lights sirf “On-Off” nahi hotin, balki wo tezi se Flash (jhapakti) hain. Is project mein hum Red aur Blue LEDs ko tezi se blink karwayenge taake “Strobe Effect” ban sake jo traffic ko hatane ke liye use hota hai.

Components Required

• Microcontroller: Arduino Uno
• Breadboard
• 1 Red LED
• 1 Blue LED (Agar Blue nahi mile toh Green use kar lein)
• Jumper Wires

Wiring (Taarein Jorna)

Common GND: Breadboard ki Blue line ko Arduino GND se jod dein.

1. Red LED:

• Lambi Taang (+) → Pin 12.
• Choti Taang (-) → GND line.

2. Blue LED:

• Lambi Taang (+) → Pin 11.
• Choti Taang (-) → GND line.

Code

// Project 9: Police Strobe Lights
// PlzPapa Robotic Kit

int redPin = 12;
int bluePin = 11;

void setup() {
  pinMode(redPin, OUTPUT);
  pinMode(bluePin, OUTPUT);
}

void loop() {
  // Step 1: RED Light Strobe (Tezi se 5 baar jhapke gi)
  for (int i = 0; i < 5; i++) {
    digitalWrite(redPin, HIGH);
    delay(50); // Bohot kam waqt ke liye ON
    digitalWrite(redPin, LOW);
    delay(50); // Bohot kam waqt ke liye OFF
  }

  // Step 2: BLUE Light Strobe (Tezi se 5 baar jhapke gi)
  for (int i = 0; i < 5; i++) {
    digitalWrite(bluePin, HIGH);
    delay(50);
    digitalWrite(bluePin, LOW);
    delay(50);
  }
  
  // Yeh loop chalta rahega: Red-Red-Red-Red-Red ... Blue-Blue-Blue-Blue-Blue
}
