Are you with Dexter? I am really concerned now that I am not going to be able to complete this project with my students because this is so erratic. I have been trying to get this fully functional for nearly two weeks. My project with them starts next week. I just noticed a new version of Bloxter, 2.1.0 and after installing it, it seems to be a little more stable. It is still not completing it 100% of the time, but it does seem to be working better. I was finally able to get it to complete the course to 100% for the first time. But again, subsequent runs of the same program resulted in failures somewhere along the code. But it is a marked difference from 2.0.0 – Did the code update to 2.1.0 address the line follower? If so tell the developers they are ALMOST there. Something however is still amiss.
One thing to note, the instructions on Dexter tell you to use the two acrylic spacers on the follower. (like the attached pic) Two goe on top of the board (they look like washers) and the other one goes on the bottom of the board (looks like a leading shield in front of the sensors.) When I assemble the pieces as instructed, it places the line follower too close to the floor and the screw heads wind up dragging. So I have to remove one or the other, (the washer or the shield) to make this work else it drags and does not work at all. I have double-checked the instructions and it is assembled correctly, but again it winds up dragging. But again, I don’t think that has anything to do with it because Bloxter is showing it picking up the correct values. The print output however is usually wrong, and inconsistent with what is showing in Bloxter under the IC2 sensor reading.
I am at my wits end, and can’t move on to the distance sensor because I can’t get it to work with the line follower.
I am using this as my base project:
