Line Follower Robot using Arduino🔥

[@hashincludeelectronics]

Guys I am observing that people are facing issue only because they are using 9v non rechargeable battery . Please don’t use that 9v non rechargeable battery because it does not provide enough power . Use some good rechargeable battery like LiPo or LiON batteries👍🏻

[@nicolassintenis4700]

hello there, thanks for you video you are already carring us through our university projekt. But in our project we need to go the track backwards. Do you belive its better going backwards or let the linefollow robot turn 180 degrees at the end of the track and then drive back. In our track the end of the line is build with a big black point. So that both sensors see black and stop. We would really appreciate an answer. Greetings from Germany

[@hashincludeelectronics]

I would suggest make a 180 turn . Right now this robot stops after seeing black big spot . Rather than stopping it , let it turn 180 degrees . You need to adjust delay for this 180 degree rotation . I don’t have robot assembled to test it . So you need to do it on your robot and see if it works . 👍🏻

Hey I was following your video to make a Line Following Robot of my own, and I have everything set up as you do in the video, but the light on both of the IR Sensors labeled POWER is constantly lit red, not green like they are in your video. Also, the robot itself is not driving (the motors aren't spinning whatsoever). I was just wondering if you knew why this was the case and if you knew a fix for this issue. Thanks!

[@hashincludeelectronics]

Thanks for checking out the video 👍🏻. May be your IR sensor power LED is red . You should calibrate the sensors by placing them on black and white surface and adjusting the knob on sensors . Check the video properly . Also make sure you provide only rechargeable battery power .

[@saladbar__]

@@hashincludeelectronics Yes my Power LED on the IR Sensor is red, I was wondering if you knew why. I'll have code that I used to test if the robot could even drive attached below, and I believe something may be wrong with that as well so if you see anything wrong with it let me know. I calibrated the sensors just as you did in the video, so I do not believe that is an issue. The robot is detecting a change when I move it over the black tape, so again i do not believe that to be the issue. I checked the rest of the video twice, and everything seemed correct according to the video. And the battery I am using is a 6v battery pack, but I tried to power the robot by using a 9v battery and by plugging it into my laptop and running the code, but neither of those work. If you have any idea as to what could be wrong, let me know. Until then, thank you for the very detailed video! Attached code: // defining the pins void setup() { pinMode(10,OUTPUT); pinMode(9,OUTPUT); pinMode(8,OUTPUT); pinMode(7,OUTPUT); } // defining variables void forward(){ digitalWrite(10,HIGH); digitalWrite(9,LOW); digitalWrite(8,HIGH); digitalWrite(7,LOW); } void pause(){ digitalWrite(10,NULL); digitalWrite(9,NULL); digitalWrite(8,NULL); digitalWrite(7,NULL); } void loop() { // code to make the robot drive pause(); delay(1000); forward(); delay(3000); pause(); delay(1/0); } And then the in a separate file I have your code that I copied from GitHub, but that too does not work.
