Using QTR-8RC sensor for black and white line following


I am also having this problem…how to code the line follower using qtr 8c so that is follows black on white and white on black lines in the same track simultaneously?

How to edit program line follow to cross white space


I moved your post to its own thread under our “Sensors” subforum since it is about a different issue and more appropriate.

Someone else on our forum asked a similar question; you can see our response to it here.

Yes i saw it,but unfortunately my line follower doesnt switch codes when it switches line…how do i solve it so that it changes parameters when line colour changes?


There are a few ways you can go about determining if you are on a black or white line. One way would be to use one or two sensors on your QTR-8RC array or strategically place additional sensors on your robot to constantly check for the color change in the background.
