Making Traffic Lights with Arduino Uno - Beginner Level (algorithm, coding, circuit design)

Learn how to make a traffic light in Arduino Uno kit. This is a beginner level project.

I found it quite interesting.

// Pin definitions
const int redLedPin = 13;
const int yellowLedPin = 12;
const int greenLedPin = 11;

// Time intervals (in milliseconds)
const int redTime = 5000; // Red light duration
const int yellowTime = 2000; // Yellow light duration
const int greenTime = 5000; // Green light duration

void setup() {
// Initialize the LED pins as outputs
pinMode(redLedPin, OUTPUT);
pinMode(yellowLedPin, OUTPUT);
pinMode(greenLedPin, OUTPUT);
}

void loop() {
// Red light
digitalWrite(redLedPin, HIGH);
digitalWrite(yellowLedPin, LOW);
digitalWrite(greenLedPin, LOW);
delay(redTime);

// Green light
digitalWrite(redLedPin, LOW);
digitalWrite(yellowLedPin, LOW);
digitalWrite(greenLedPin, HIGH);
delay(greenTime);

// Yellow light
digitalWrite(redLedPin, LOW);
digitalWrite(yellowLedPin, HIGH);
digitalWrite(greenLedPin, LOW);
delay(yellowTime);
}

This is our last minute project. Really good idea.

Keep up the good work. 👍👍👍👍

Bhaiya i need a program and full video on advance traffic clearnce for emergency vehicles transmitter (in emergency vehicle) should have 4 switch to notify the receiver that from which side the emergency vehicle is coming please make detailed video on it

[hgupta]

This is very easy to understand. Thanks for sharing 👍

Is it okay to use Arduino mega 2560 that's what I have?

[jameseadie]

i am confused i did exactly the same as in the video but it says "output was not declared in this scope" please reply

[md.jubayerofficial]

Sir please share the code for this project, its urgent.

[hlgovinda]

Can I see these traffic lights on screen from 1 or 2 km ? Please say

[bhanuprakash]

Bro for 4 way traffic control what is the process bro

[piston]

Sir please share the code for this project, its urgent.

[JorbGupta]

Sir plz tell me what is software use coding

[slimyskele]

this is very easy to understand

thanks for the vid

[surajrauniyar]

What the value of register, please help with that any one

[dharamvirgupta]

It is creative & Interesting.
Good.
