I’ve unsuccessfully searched for some help on using an optical sensor to make a line following robot. I utilize blue “gym tape” on the floor of my shop. We have a group of students who are about to start working on this project. The kits are brand new to our district and have been awesome. But…I’m hitting a dead end on this one. I measured the floor with the Hues menu and the floor is showing as 0 and the blue line as 240(if I did this correctly). So, it seems as though the robot is seeing those colors. I am aware that you can write the program with it either detecting the color (red/blue/etc) or seeing the Hue value. Unfortunately, I’m striking out.
If there is anyone willing to help out with a few programming examples, there are several hundred Middle School kids who will be appreciative!
