Please SUBSCRIBEto my channel for more projects.

This project is about Smart street light, street light will turn on while vehicle is passing through it.
here we are using 4 IR sensors that senses the position of the vehicle,each IR sensor controls 3 LED's. When vehicle passes by a particular IR sensor it senses the position of vehicle and gives its signal to the arduino board and it will turn on the LED's.

ADVANTAGES:

If we uses this idea and implement to it in our society it will be helpful in saving enough amount of electricity and off-course money.

## Step 1: Components Required

1. arduino uno
2. ir sensor (4)
3. 10mm LEDs (6)
4. connecting wire
5. foam board

## Step 2: Upload the Program

download and upload the program in arduino uno

## Step 3: Connect the Circuit

Connect all the components as given in the circuit diagram.

ir sensor 1 ---> 2

ir sensor 2 ---> 3

ir sensor 3 ---> 4

ir sensor 4 ---> 5

connect all ir sensor's to +5v and ground.

the positive pin of leds are connected to these pins of arduino.

led 1 ------> 6

led 2 ------> 7

led 3 ------> 8
led 4 ------> 9

led 5 ------> 10

led 6 ------> 11

and finally all ground pins of led connect to the ground of arduino.

## Step 4: Build Suitable Structure

To make these poles as given in above picture, use foam board and glue.

and you may also use black chart to make a road and wooden board for the base of pole.

I need some help sir.
You have given the pin configuration and conenctiom for only led and ir sensors! Can you please gove the circuit diagram from the input terminal and all other terminals used please! Like if there is a resistance or where is the input power given and so on! It would be of great help sir

Thanks for the project with detailed instructions, but I think your code is wrong, the leds are working opposite to what it should do, I made some changes to the codes and i am providing my code below for those who are facing the same issue.

USE IT , 100% WORKING

Anyone,s whose project is working opposite(i.e. led's are turning off when an object is coming close to the IR sensor), Please use my codes it will work perfectly ,
