By "line follower" I assume you mean that a line is painted on the floor and the robot follows it. In that case, you need two sensors, one for right ,another for left.
If that is not the case, we need more explaination.

Try this place, I'm pretty sure it's what you're looking for. And if you watch the movie you'll see that the results are quite good. **broken link removed** Go to the bottom of the page and click "An inexpensive infrared line sensor for the MIT Handy Board." That should be what you want. Let me know if this helps. :wink:

Line Follower

You only need one IR transmitter and one IR receiver to track a line. For example you place the robot to the right of the line. Program a uPIC like 12f675 to control two motors. When the IR pair detects no line it turns left and when it sees the line turn right. Then it zig zags back and forth.

I personaly just never really liked the zig-zag type. If you watch the movie of the one I posted, you'll see why I love that one. I've seen the zig-zag ones, and although they might be easier to build, they aren't nearly as fast and steady as this one. :)
