HiTechnic V2 color sensor

[brybrybry]

Is HiTechnic V2 color sensor on NXT able to trail a strip of LED lights? Would this be possible? If so, how?

There's no straigthforward way to achieve this.

The only way to do this is to use sensor to detect the path color, and if the color start to deviate, then change the direction back to the track.

i have a question regarding that, how do i program the nxt such that it knows wether to deviate back to the right side or left side. For example, it goes off course towards the left and detects a change in color, how do i tell it that it has to turn right instead of left.

Thanks

You need two sensors.

If one on left start to detect less color, it means it bent to left.

[brybrybry]

oh no, so this means it is almost impossible to trail a thin strip of LED lights?

Another possibilities, if you turn left, and it get worse, then turn right.
