Line follower code nxt robot arduino uno source code
There are a lot of possible difficulties that can be set up for you in a contest. This will help you test your code then and there. It is really helpful if those LEDs are right on top of the sensors.
Now your code should have these lines too. This code should be good for any linear track with normal bends. But this is not going to work if your track has right and acute angle turns.
Programming a Line Follower Robot Jun This is a follow-up on my previous post Line Follower Robot - Build it from scratch. This reflected beam is picked up by the IR detector and its conduction increases and hence a voltage variation in the output pin 0v for absence of IR rays and 5V for maximum intensity.

The IR emitter emits a constant IR beam. With the calibration values at hand, you can start programming your robot. If you had used the circuit diagram that I posted or something similar, you should be having some indication LEDs at the output of the comparators like this one here.
If you had used the circuit diagram that I posted or something similar, you should be having some indication LEDs at the output of the comparators like this one here. But we will discuss some of the most common one listed above in the posts to come. I used a black chart paper to make the track and stuck it over white one.
This is when you have to tweak the direction logic a little. The next step is to sit with a pen and paper and make reading from the track that you just made. It is really helpful if those LEDs are right on top of the sensors. The next step is to sit with a pen and paper and make reading from the track that you just made. I placed the output LEDs green directly above the line sensor to avoid confusion.
Here is the track that I built for my line follower. I placed the output LEDs green directly above the line sensor to avoid confusion. I even mentioned in my previous post the maximum distance between the sensors should not exceed the width of the line.
