Good video and also good coding. Thank you very much for your wonderful work. Still i have a question. Do i also need to supply the arduino with a 5v battery or only the motor driver? The dc motors run faster if i supply the arduino with a seperate supply but i do not know if this is safe or does it damage the arduino module.

Bro I have a problem the line following robot is responding to every object instead of black only i tried to change the potentiometer reading by rotating the cube but nothing happens
Try to change the intensity of ir sensor 😁 and brother never use ready made ir sensor coz there vulnerable to light... Better try to make your own one.. And it's really a easy task to make one...
In the video, he has forgot to remove the jumper, while connecting external power supply to the shield. But how on earth did it work?? I think your shield will work now.
Hello! Thank you for making this fascinating project! I want to make a project similar to this, but the motor drivers on Amazon do not have pin headers where you plugged in the IR sensors at timestamp 3:03. Did you solder pin headers into your board on the lower right side?

Hey bro! I did everything that you said. And even I checked the code..one doubt is why did you set logic 1? And also.. my robot doesn't follow the line.. it moves but doesn't follow the line. Can someone help me out ? Thanks in advance
First of all, wiring is essential! You may need to adapt either the code or the pinout. Beware also of the sensors output! If the voltage difference of level is too low, you may not recognize the line. Another point is that I don't understand why in the code we have ANALOGREAD : if(digitalRead(left)==0 && digitalRead(right)==0){ else if(digitalRead(left)==0 && !ANALOGREAD(right)==0){ else if(!digitalRead(left)==0 && digitalRead(right)==0){ else if(!digitalRead(left)==0 && !digitalRead(right)==0){ I have not tried it but it doesn't look normal.
The same problem occurred! Even I changed that one '!analogread(right)' into '!digitalread(right)', Then also It was going straight and didn't follow the line. Also, I modified the path from narrow to broad, and the same things happened, It was going straight. The speed is also very high.

@@testname367 W8888888888888888888888 this REALLY works??????????????????????????
@@testname367 Where are motors 2 and 3? u r basically using just 2 motors for a 4 wheeled vehicle. U r not specifying what colour IR Sensors are supposed to be following. There are a million other mistakes. This code is wrong on so many levels!!! No offence but I don't really think it will work.
which kind of chassis and wheel have you used in this project ? i mean to say what kind of meterial is used to made this chassis and wheel ?
Material doesn't matter...just upload the right code and make right connections
