IR Sensor and LED with arduino (with code explained) | All digital sensors | Arduino tutorial 4

[@BromideBride]

This series [and I'm only four videos in] explains with more clarity than several books and online tutorials I've tried to follow. Thank you so much.

[@techathome]

Thank you for your feedback ❤️. It motivates us to make more...

[@______6796]

ok

[@etikalarani7231]

You are explaning very good like our sir👌👍👍🏻

[@techathome]

Thank you ❤️

Hi im Trying To Make A Vending machine using arduino but i have problem with the code, i want to make it when the ir sensor detects it 2 times the light will turn on but it wont work the light keep blingking Could u Help?

[@techathome]

Can u share the code u have used over the mail

[@anothernpc8246]

tysm this is very comprehensive

[@techathome]

Welcome ❤️🙂

Why can't the IR sensor detect my hand even when I put it in front of it as an object? If I adjust it, the IR sensor will detect, but it never turns off when I remove my hand. And if I adjust the IR sensor again in the opposite direction, it doesn't detect anymore. What should I do?

[@RamaLaxmiLAKKADUSU]

IR sensor was damage the IR sensor was detect 10cm range😊

[@venkateshnaik4064]

hi sir, iam getting out put as 0 and LED is contineously glowing even if i vary my hand infront of sensor. Please help me in this regard

[@techathome]

In the sensor there is a small potentiometer, try to rotate it on both sides and change its sensitivity

[@nelomedia805]

Hello! I presently have a working temperature sensor and would like to activate addressable LEDs at different temperature thresholds, example; blue 0-80F, green 81-120F, yellow 121-200F, orange 201-250F, and red 251F and above. Would it be possible to articulate how to do this in the code so i can add it to my existing sketch? Thank you so much

[@techathome]

Yes, that can be done using if-else statements. You can send your existing code on our mail: [e-mail]

[@tharuneee3rdyear847]

In tinkercad, after simulation how do I active the IR sensor

[@someonexteaches]

u cant activvate ir sensor in tinkercard

[@kemaketseforkssebitiela3089]

When to use analog read or write?

[@techathome]

AnalogRead - To read voltage drops from analog sensors(Potentiometer, Temperature sensor etc): kzbin.info/www/bejne/opiQgoh4gdJsm7c AnalogWrite - To generate PWM signal of required duty cycle: kzbin.info/www/bejne/jaepnoyvbJp9q5I

[@rodelalfonsobautista3729]

can I use multiple led lights?

[@techathome]

Yes

[@chris-ut4hs]

Hi, where you got that buzzer from?

[@techathome]

You can get in electronic shops Also in Amazon

[@thameemulazarudeen9692]

What are all the conponents used can you give me the name of the components used

[@techathome]

Arduino Uno, IR sensor, LED

[@richardlange9094]

I have tried to duplicate this , but my sensor never goes off. I have checked the wiring and it is same as yours. I am using an Arduino Leonardo board. Any recommendation on what I am not doing correctly?

[@techathome]

On the sensor module, there is one blue colour potentiometer screw to increase or decrease the sensitivity. Rotate that and reduce sensitivity.

[@richardlange9094]

@@techathome Thanks for the input. That solved the problem. But the sensor range is too short. So I am going to try a 2 piece sensor (sender - receiver). Once again thank you very much for the help.

[@techathome]

Welcome

[@tahaibrahim9564]

Is it the same with PIR sensor?....I tried with that but didnt work.

[@techathome]

Yes same , PIR sensor is also digital, digitalRead should work

[@vaishnavivanga4048]

Hi Sir I Can't Open the link given for code and circuit...

[@techathome]

It is compressed file, you have to extract it using winRaR or any zip extractor. If not, send request on our mail, will share again.

[@rohanshiragaonkar917]

Thank u sir

[@anjulovesdoracakes22]

can you give more detailed code?

[@techathome]

Code link is provided in description

[@johnsangeetha9203]

The program is not been uploaded and many error are coming but the program is correct

[@techathome]

What is the error message? Can you also send screenshot on mail: [e-mail]

[@thejask4749]

IR doesnt get the power and even the reading is zero throughout

[@techathome]

Have you connected VCC and gnd correctly?

[@keshavkeshari6892]

In online simulator , I can not find ir sensor . If you know where i can access ir sensor ,comment here please.

[@yaduvanshiji9]

Tinkercad it's free and has all components

[@sahilirane1303]

pls explain breadboard connections better

[@techathome]

[@minskie]

Can you tell me how power on a dc motor the same way with an IR sensor?

[@techathome]

You need to add few lines to run DC motor instead of LED. Refer : kzbin.info/www/bejne/j2mrnpWIZshql8k
