    This program will need to be tuned for each robot.

      The variable you will need to tweak is "Tp" which stands for "target power". Setting that to a lower number will cause the PID output to hover around a lower power setting.

      It really just depends on your lighting. I would recommend looking at the values from the sensor at the lightest point and darkest point and divide the difference by 200 to get the gain for kp. The other two have to be done by trial and error.
