I’m trying to use the GPG3 in conjunction with the line follower and I’m having some calibration issues. Is the status light of the line follower supposed to flash red? If not, how can I remedy this?
If so, I’m not sure why perfectly white surfaces (sheets of printer paper) are being read as 800s and 700s (it usually looks like [857, 784, 781, 784, 838]) when I run the calibration. In addition, to this black lines are read in the high 900s (usually something like [995,978,977,984,996]). I suspect it is this similarity that causes the read position to be [1,1,1,1,1].
Can someone offer assistance? Thanks in advance!
