I set up a line circuit for my students but I was unable to make it work. The line trackers are not working properly, they do not detect any line when I connect them to a VEX v5 Brain.
Is there any solution to this issue? Am I doing something wrong?
It hard to see the brain well in the video, but it does look like perhaps the connector for the line tracker is not fully seated into the 3-wire port on the brain. Make sure you test with analog input selected. Typically white or black electrical tape would be used as the “line” for the sensor to detect, the sensor is usually about 1/4 inch above the line.
