how to line square

[amberneb]

I have made many line squaring programs in robot inventor but when i try to make one with Pybricks the sensors sometimes don't register the line. I have tryed multiple amounts for the reflected lights and it does not help. I would love to see a line squaring program that works. Thanks

Could you please post the code you are using, and maybe a link to a video of what isn't working?
