In order to make killalot work, you have to connect the jumpers with this configuration: three line sensor, three proximity sensors and blue leds.
See figures (1) and (2) in this repos.
If your robot has soldered flipping the two motors, please remove // before this statement in killalot.ino
//#define FLIP_LEFT
//#define FLIP_RIGHT
With our robot, we set TIME_TO_WAIT to 2.7 seconds, because our calibration phase requires 2.3 seconds; please consider to make some test before Fighting.
Therefore modify this statement as you wish
#define TIME_TO_WAIT 2.7
