    Hey, can you point me in the right direction to program this bot? I'm using five QDR1114 sensors. Hardware is working properly, 4v or greater detects black, less than that detects white, thanks.

    What inputs are the sensors connected to?
    Which sensor is which input?
    What outputs are the motors connected to?

    Did you buy it as a kit? link?

    Thanks zg3409, sorry for the late reply.. I managed to get the line follower working after some more research. I used an Arduino Uno and this motor driver shield http://www.dfrobot.com/wiki/index.php/Arduino_Motor_Shield_%28L293%29_%28SKU:_DRI0001%29 Used Analog inputs 1-5 for sensors e.g Sensor 1 to A1 (leftmost sensor), Sensor 3 to A3 (middle sensor) and Sensor 5 to A5 (rightmost sensor). PWM from arduino output pins 5 and 6 and motor direction from pins 4 and 7 (digital pins) .
