Line Tracking Sensor - 5min Tutorials

This is a tutorial for the Line tracking sensor.
Line tracking sensors are often used for making line following robot cars and other arduio/ raspberry pi projects.
In this video, I explain the working of a line tracking sensor, and show how to hook up, and code them, and then finish off with a little test of the line tracking sensor.

found this channel randomly,and videos are awesome with well explained programs as a beginner . :)

[@Fungineers]

Thanks man! How did you find the channel?

[@sarathkumarps6473]

I was searching infos for my final year project ,and none of videos was much helpful till now,and found one of your video with pgm explanation.and you have earned 1 subscriber 🤩.

[@imstudent8895]

It helped, thank you.

[@latacui6773]

Thank you for your clear explanation! I'm an amateur and starter and hopefully can learn more from you

[@DreThePlug]

Niceeeee video!

I know that black surfaces absorb most of the visible light while white surfaces reflect most of visible light. But how do we know that the same applies to IR light too?(I read a Quora answer and they said it depends on the black surface)

[@Fungineers]

Light is light..right? ;)

[@ayyubshaffy3612]

@@Fungineers yeah.. but Infrared light isn't visible light..
(srry if im sounding dumb but im a newbee)

[@anondimwit]

Ayyub Shaffy doesn’t matter if it is visible also with some cameras we can see it

[@ronantremoureux3743]

Oh we can use it to count a number of turn of a motor, it can be a way of using it 🤔

[@goku445]

Not sure if it is fast enough for that purpose.

CODE
void setup() {
Serial.begin(9600);
}
void loop()
{
Serial.println(digitalRead (8));
delay(500);
}

[@rodrigo-tj1gf]

What is the datasheet on that ?

[@CorpusCharlesChipStevenSCorpus]

Can it change to detect black surface instead of white?

[@Fungineers]

Yea

[@CorpusCharlesChipStevenSCorpus]

Fungineers How?

[@gerardofranco-mora257]

Vintage Gaming its boolean just make 1 true and 0 false or vice versa in your code.

[@melissevillanueva8746]

Where did you put the other two wires in the arduino?

[@072-o1e]

Ground and 5v

[@wahbiyassine3488]

can i use it in line follower instead of Qtr

[@Fungineers]

Qtr?

[@wahbiyassine3488]

@@Fungineers QTR-8RC Reflectance Sensor Array

[@Fungineers]

Yeah those are basically the same things just tiny.

[@drkrishnaprasadsharma6349]

How to control the sensitivity

[@Fungineers]

Can only control distance with the knob

[@farestarik4462]

please, this sonsor works in the dark ?

[@Fungineers]

I think so...havent tried.
