For line tracker, IR is commonly used, but I used red light led, and found it better than IR.

Sorry, I lost all my data as I quitted uni, and I don't know where to find it. But the fact that I just replace IR led and IR receiver by red led and phototransitos. I built it as indentically as many other IR transceivers.

Hi!
falleafd, why do you find that Red is better than IR ? Is it simply for troubleshooting because you can see it ? |

Red led is stronger than IR, and it can easily receive by phototransistors. You can put xmit and rx package of Red led + transistor outdoor, and you still receive good signal. But with IR transceiver, it may cause some noises. You may do experiments to see that.

ive made a line follower. no programing at all. it was for my year ten project. i wish i had skills and resources at the start so i could program it. neways, i used a simple ir detector/emmiter. the hardest part of line following is the ambient light hanging around the sensors.
