    The line sensors don’t seem to want to follow the line. When I hooked the sketch up to Serial Monitor and printed out the values rLevel = rSen.read(); lLevel = lSen.read(); cLevel = cSen.read(); I get about 940 when there is no black line and it is just sitting on a white poster board.

    When I move the line sensor directly under a black sharpie line or black electrical tape, I about 980. This is true even when very close. If I put my figure over the sensor I get about 300. It seems like the sensor just isn’t giving much feedback when it is on a black line.

    Any help would be appreciated.
