HELP! line tracker not working!

Please help me! I recenly got the line tracker kit. I made a program for the line tracker kit, but it didn’t work, so I took out my video camera to see if they were working. Sure enough, the line tracker wasn’t working. Ill show a pic later

Please help me! I can’t figure out why it’s not working!

Thanks for your help!:slight_smile:

Can you print out the Values returned from each of the Line Trackers??

What is the Value when over a Light Color, What is the Value when over a Dark Color??

Can you post your Code??

How do I post the program? I’ll do a test today.

Thank you for your help!:slight_smile:

I have done and test with my broken line follower. When running the value is 21. The IR light does not go on. When I take a TV remote and press a button while pointing it at the line follower, the value jumps. I used the line follower test program that came with the software.

Thanks for your help!

Could there be just a loose connection? Should I take apart the line tracker to look at it? Or should I send it back?

Since I’m guessing it’s a code problem it would be best if you could either upload the code in the form of a file or do several “PrintScreens” so we can see the code.

Actually, it sounds like he has a dud line sensor. If the IR light does not come on, then it won’t work correctly. The picture clearly shows the IR LED not working on the right-most sensor, and he indicates that an IR remote makes the value change.

Since the software doesn’t control the LED in the line tracker module, I don’t see how software could be at fault. It could be a faulty module, wire, or connection.

Things I’d try:
*]Remove any servo extender cables you may be using.
*]Make sure the line tracker module connector is well-inserted into the microcontroller.
*]Try using different ports on the microcontroller to see if you’ve got a bad/marginal port socket
*]Beg/borrow a line tracker to substitute for the defective one and see if your problem clears up.
From the picture and diagnostic info already posted, though, my guess is that it is a dead module. If it is still under warranty, you should ask for a replacement. If it isn’t still under warranty and you’ve got some basic soldering skills, you may be able to replace the IR LED yourself. Since it still reads values OK (according to the IR remote test), this might restore it to health for way less than buying a new set.

Best of luck,

It appears I misunderstood his problem, after re-reading his posts I think Quazar has the right idea.

I agree with corpralchee, that Quazar has the right idea.

I tried everything that Quazar said and it still didn’t work. I just got it a few days ago, so it should be under warranty. I’ll just have to send it back.

Thanks for your help!:slight_smile:
