Sensor used to detect black tape

[Klitzie]

Just wanna ask how to build a line sensor that can detect only black tape, so that my line follower will be always stays at the center of the tape. Any suggestion or ideas would help me a lot...thx

We have no idea what you know about robotics or electronics.

If you are new start with reading about sandwich and whatever else you can find at
https://www.robotroom.com

The author has several books on robotics that you may find helpful.

If you are not new tell us what level you are at and we can respond at a level that is in keeping with what you will understand.

i think you will find a lot of answers in my robot navigation page:
**broken link removed**

More precisely take a look at the "Line tracking sensors and algorithms". This article should tell you all you need to know for your project.

Qrd1114

I decided on the QRD1114 sensor to detect the black line. I'm writing an article on how I built the robot. Part 1 specifically discusses how to build a multi-element sensor array with QRD1114's. Get it at www.PICRobots.com/Article.pdf
