Hi everybody, I am building a line following robot but am facing a problem on the detectors since I don't know what type of infrared led and detector I must use. I searched on the net about the IR detector and LED but I found a lot of detectors some how acting as a transistor and some working as a diode…well that’s my schematic for the robot down if anyone have an experience on the line detector please assist me and thanks a lot
