• Traffic Light using Arduino - A Beginner Project

• 
  

• Introduction

  In this project I will Demonstrate you how to make a very simple and very cool traffic light Using Arduino.

  This project will involve using a little a bit of code and a very simple circuit that’s great for beginners.

  The video further down this page will go through all the steps to completing this cool traffic light project.

  This simple little project uses an Arduino and some LEDs to replicate a traffic light. It uses code as an internal timer and continues to run until you cut the Arduino's power supply.

Working on Basics

The LED have been powered by Arduino UNO (Board). It contains a code which uploaded to the board. And once it simulated LED Start's blinking like a traffic light. In this 15 Second will for Red Light 6 Second for Yellow Light (In my Project Blue) and 20 Second for Green Light.

Usage

There is multiple usage of the project:-

1. If you are beginner so it is a intro to arduino

1. You can Make a real but small Traffic Light using it

1. You can also add more LED and Can change as per your usgae

code 

int red = 9;

int yellow = 8;

int green = 7;

void setup(){

  

  pinMode(red, OUTPUT);

  pinMode(yellow, OUTPUT);

  pinMode(green,  OUTPUT);

  

}

void loop(){

digitalWrite(red, HIGH);

 delay(15000);

digitalWrite(red,  LOW);

  

  digitalWrite(yellow, HIGH);

delay(1000);

  digitalWrite(yellow,  LOW);

delay(500);

  digitalWrite(yellow, HIGH);

delay(1000);

  digitalWrite(yellow,  LOW);

delay(500);

  digitalWrite(yellow, HIGH);

delay(1000);

  digitalWrite(yellow,  LOW);

delay(500);

  

  digitalWrite(yellow, HIGH);

delay(1000);

  digitalWrite(yellow, LOW);

delay(500);

  

  digitalWrite(yellow, HIGH);

delay(1000);

  digitalWrite(yellow, LOW);

delay(500);

  

digitalWrite(green, HIGH);

delay(20000);

digitalWrite(green,  LOW);

//  

digitalWrite(yellow, HIGH);

delay(1000);

  digitalWrite(yellow,  LOW);

delay(500);

  digitalWrite(yellow, HIGH);

delay(1000);

  digitalWrite(yellow,  LOW);

delay(500);

  digitalWrite(yellow, HIGH);

delay(1000);  

  digitalWrite(yellow, LOW);

delay(500);

  

  digitalWrite(yellow, HIGH);

delay(1000);

  digitalWrite(yellow, LOW);

delay(500);

  

  digitalWrite(yellow, HIGH);

delay(1000);

  digitalWrite(yellow, LOW);

delay(500);
