@bhaveshg1000 I used an infrared emitter and detector pair (they look like black and white LED's at the front of the robot). The emitter constantly shines infrared light at the ground in front of the robot. The white surface reflects this light but the black line tends to absorb it. The detector can sense the different infrared light levels being reflected. This signal is amplified and sent to the microcontroller . Then based on the voltage level the micro can determine the robots position.
@FerrarisRock Yep its a 2nd year college project for my computer and electronic engineering course. We dont have grades in Ireland, is grade 10 school or college?
How the robot learned that it the start point after returning.???

@vickyron1 it knows it's back at the start when it finds the end of the line for a second time

This is great! My buggy that I'm building just won't stay on the line. Could you send me a copy your basic code so I can see where I'm going wrong?
