🚨 Arduino Police Light Flasher Project — Best DIY for Beginners!
Hey friends! 😊
In this video, I’m sharing one of the best starter projects for anyone new to Arduino — a simple but cool police light flasher. All you need are a few LEDs and an Arduino board, and you’re ready to go!
This project helps you understand how digital pins work, how to blink LEDs in a pattern, and introduces basic timing using delay() — perfect if you’re just getting started with coding and hardware.
🎯 What You’ll Learn:
How to connect RGB LEDs to an Arduino
Using pinMode() and digitalWrite() functions
Creating light effects with delays
Building your first real Arduino circuit!
🧠 Project Description:
We’ll control three LEDs (Red, White, and Blue) wired to pins 13, 12, and 11. By turning them on and off in a timed pattern, we’ll create an effect just like flashing police lights!
🔌 Circuit Connection:
RED LED → Digital Pin 13
WHITE LED → Digital Pin 12
BLUE LED → Digital Pin 11
GND of all LEDs → GND rail on Breadboard → GND pin on Arduino
💻 Copy & Paste Code:
void setup() { pinMode(13, OUTPUT); pinMode(12, OUTPUT); pinMode(11, OUTPUT); }
void loop() { digitalWrite(13, HIGH); digitalWrite(12, HIGH); digitalWrite(11, LOW); delay(80);
digitalWrite(13, LOW); digitalWrite(12, HIGH); digitalWrite(11, LOW); delay(80);
digitalWrite(13, HIGH); digitalWrite(12, HIGH); digitalWrite(11, LOW); delay(0);
digitalWrite(13, LOW); digitalWrite(12, HIGH); digitalWrite(11, HIGH); delay(80);
digitalWrite(13, LOW); digitalWrite(12, HIGH); digitalWrite(11, LOW); delay(80);
digitalWrite(13, LOW); digitalWrite(12, HIGH); digitalWrite(11, HIGH); delay(0); }
📦 Components You’ll Need:
Arduino UNO
Breadboard
Jumper wires
Red, White, and Blue LEDs
Resistors (220–330 ohm recommended)
USB Cable for Uploading Code
