IR array
Read the analog value of the IR sensors at the
bottom of the robot. The also-called line following
2013-05-15 10:47:17 +02:00
sensors are a series of pairs of IR sender/receiver
used to detect how dark it is underneath the robot.
The information coming from the sensor array is stored
into the Robot.IRarray[] and updated using the Robot.updateIR()
method.
