Use 3.0 library of qtrsensor....use library manager to install 3.0.0 ​@@ssiddhaarthroboticsandauto1230

[@erembirkan6388]

Mert it is so nice to see Turks running the robotics! I love the stuff you are doing,

[@osmanbelder1483]

bu konuda izlediğim en anlaşılan vide tebrik ederim

[@gorkemozgurgenc2700]

Türk olduğunu tahmin etmemiştim saol çok iyi video

[@nihalkeetha]

Even its great that you are saying how to install library in the same video seriously bro u have a very god thinking skills

[@ajtheinventor3998]

Sup!

[@nihalkeetha]

Dude your awsm man you just created ur own webpage.. though your subscribers be less but you have all the things which a pro you tuber has like knowledge, webpage, cool fans like me and all

[@nihalkeetha]

You deserve it bro

[@TNG88]

many thanks for this great sharing :-). To new readers: you must use the OLD QTR-sensor v3.0.1 from on Aug 9, 2018. V4 is rewrote according to Pololu BrandonM. The error is "QTRSensorsAnalog does not name a type" if using V4

[@bechirjradi5275]

thank u for this great comment

[@itsjpr999]

ur a god bro!

[@harshithsgowda68]

Thanks a lot bro

[@surajsinghshekhawat1818]

Then use 3.1.0

[@brayansantos6852]

this video helped me get a good grade on my final. thanks man !

[@weekendprogrammer7545]

Brayan Santos Did it work without out USB

[@brayansantos6852]

yeah it did, just make sure you use a higher voltage battery I used a 9v battery in my case

[@manavsaini1920]

What you have put at last a yellow box like thing? At 8:15 in video.

[@altaykilic2142]

Those are DC Motors.

[@DTVideom]

Why did you connect it to analog pins when giving 8rc digital output?

[@pedritoevil]

Sketch uses 4056 bytes (12%) of program storage space. Maximum is 32256 bytes. Global variables use 63 bytes (3%) of dynamic memory, leaving 1985 bytes for local variables. Maximum is 2048 bytes.

[@tamiltechthivvyan5979]

please put the code

[@avinashraj4102]

U r great thanks for this wonderful video I was searching for this video finally I got it's such a wonderful video better than any other video of the same kind thank you

[@wamiqfahim9123]

Phenomenal actually. Would appreciate if you could explain the coding behind the PD.

[@wamiqfahim9123]

Oh I know what you mean. Just trying to learn the concept of PID. it will most probably help.:D

[@engineered_insanity]

Thats a very detailed video. Thanks for the code and all too

[@ejazanjum1498]

MERT KILIC I AM YOUR FANNNN 👏👏👏👏

[@mashrafi_m]

Seriously bro, AWESOME!!!!

[@hamzarehman112]

what is the distance between the sensor and the surface????????

[@dipanshuaggarwal7089]

made me make this project bro! great for giving the program thnx bro!

[@Thinkdifferentsagnic]

Please answer this! Why is your error declared as position- 2000? Then for any position of the line the error would be same. It should be something like - goal- position isn't it?

[@saliksheraz6236]

Awesome work bro

[@NaraBage]

can i use tcrt5000 sensor instead of qtr sensor and use the same code?

[@jeyapravin5775]

The programming part is very difficult to understand. Can you suggest this line follower with the help of XOD.

[@kdsatya_6]

can u help me?, i always get Compilation error: no matching function for call to 'QTRSensors::QTRSensors(unsigned char [5], int, int, int)', what things need to change?, ASAP pls 🙏🙏

[@kishanpatel5332]

Superb , unique method But ,Is it edited video❓ or it's original speed of line follower

[@sumeshkumar9086]

also sir about drone like robot controlled by android or voice detection sensor and ur explanation is superb sir and thanku sir

[@nafisfuadjim4817]

Can this robot only follow a continuous black line without any gap???? if there is a gap of white (5 cm) in the main black line of the track..then will this robot follow it?

[@metetabanl4467]

çok eğitici bir video olmuş tebrik ederim.

[@ogjarheadd]

I have the Arduino software version 1.8.16 and a lot of lines in the code have error messages but i followed the instructions exactly as they were on the video. I have both libraries installed but there are still error messages. Could you possibly update the code?

[@Wanderlust1342]

which batteries are best for this project?

[@nrares21]

How are you using the QTR-8RC board which has digital output and have the robot working when you wire the sensors to the analog inputs????????

[@ujjwalsinha4172]

Sir, have you used separate code for the PID control during the coding of arduino UNO

[@xravern4617]

Can you provide modifications for l298n?😊

[@coralied506]

hi ! I appreciate very much your video, it is one of the most precise that I could find, I have the sensor but I do not know where I have to put the resistance provided with? thanks a lot for your help :)

[@ratnesh5630]

Plz tell me How to use IR sensor Instead of QBR sensor

[@gauravyfrkumar8884]

From where i will get qtr -8 rc reflectance sensor please, suggest I have gone to all places in my hometown patna , but i don't found this sensor

[@annietirado5198]

Thank you so much! a blessing for me!

[@harditsingh8881]

If we attach 4 motors there will be different codes or not?

[@m.redzwuan8994]

great video.. i have a question, does it need 2 dc motor or can i only use 1 motor? and also can i use different chassis (eg RC chassis)

[@abir95571]

could you give a link where i can understand , the reflectance sensor . Coz i am curios why do we need array of 5 sensors why not 1 or 2 sufficient ?

[@akbarrajani121]

Thank you very much for your work

[@mihirpanchal7231]

does it necessarily require QTR-8RC sensor, or any other 8 array sensor will do?

[@somachowdhury7539]

I wanted to know if you have used PID in the line follower?

[@ahmetbesmi7137]

Hi! I really like your guide and I have a question. If I were to use 4 DC Motors would a single 9V battery be sufficient enough to power the robot? Thank you!

[@shubhrachatterjee]

Can you please suggest me the changes in the code if I use an IR sensor array similar to that of QTR 8RC sensor but not the exact one shown in the video.

[@ramyashree8162]

hi there, we have done a line following robot watching this vedio even though we had no knowledge about arduino, thank you so much for tat,we cant figure out the way to run the robot without its USB port connected to laptop after uploading the program.can u suggest me how did u make ur robot wireless??

[@arshiyajahan1996]

the same thing is happeningt with me also! when i am removing the usb port the wheels arent working! can there be a solution for this or an alternative?

[@simonestaco8421]

when i remove the USB port the motor doesn't work. help me please

[@nanalaly]

Try to remove the pwr jumper and try

[@tanmoyroy6704]

Probably I'm facing the same problem. Has your problem been resolved?

[@utkarshsaxena7633]

an adapter point is given u can plug in a 9V adapter or use a 9v battery to power the arduino u can attach an adapter pin to the battery n power it....

Can i use L298?

[@sumitsatyam9056]

We have a 12v Dc motor ,5v motor shield and 9v battery supply,How can we configure our robot from that ? or we have to use dc step up module and change the motor shield to 12v?? Coz we have to move robot to a inclined surface!

[@neilmitra4627]

Quick question isn't powering the arduino with 9v bad because it is being powered by 5v?

[@ishmamwahid5321]

sir , Do i need to install another library if I use L298N motor driver(the red colored one)?please could u answer as soon as possible with specified reasons.

[@hamzasaber880]

can i use IR sensors instead ? of course i'm not gonna use the Pololu QTR Sensor Library (unless it is compatible with IR sensors)

[@weekendprogrammer7545]

Hi its a very nice video first of all, Actually I am not having QTR 8RC sensor can i use the IR sensor array insted and we dont need any Library for it unlike QTR 8RC? or do we require any library file plz reply fast needed the info for an competition

[@nehalanwar6904]

Can we use normal l293D motor shield , instead of adafruit motor shield ?? please guide.

[@akbarrajani121]

Love the music. What song is it?

Thanx :) appreciate it

[@ThePhildozer89]

Pretty cool! I have a question though, do you know of a way that you can use this code and then have the robot stop when it reaches a solid black line?? I am working on a project now that this would be helpful for and I'm not so good at coding and figuring this stuff out.

Hello I have a question your link for the line follower sensor give an other board (one with 8 sensors) and I have that board can you please help me with that. Thanks fir the nice video I use now 6 of the 8 Sensors into A0-A5

[@sajjadpirsabahi9632]

The QTR-8RC reflectance sensor array requires digital I/O lines to take readings. qtr 8rc works with analog i/o too?

[@sudattsdeadchannel3495]

its is 8 / 8A WHICH USES ANALOG PINS. ITS NOT THE 8RC MODEL BUT THIS VIDEO HE TYPED SIMPLE 8/8A AS 8RC

[@pranabsarma18]

is the line follower this much fast or you have forwarded the video?

[@조아홍시-l8k]

hello, will this line follower robot work when I use 4 wheels instead of 2 wheels? and if I have 4 wheels, do I need two qtr 8rc sensors? I hope not, because I only bought one and I don't have any time to buy another....please give me a respond, thank you!
