updateIR()

Description

Reads the values of the 5 IR line-reading sensors on the underside of the robot and stores the values in an array. This array can be accessed through Robot.IRarray[]. This function needs to be called from the Control Board.

To obtain the reading from a specific IR sensor, use IRRead() on the Motor Board.

Parameters

none

Returns

Robot.IRarray[] : contains the values of the 5 sensors

Examples

#include <ArduinoRobot.h> void setup ( ) {
  Robot.begin ( ) ;
  Serial.begin ( 9600 ) ;
} void loop ( ) {
  Robot.updateIR ( ) ; // update the IR array
  for ( int i= 0 ;i<= 4 ;i++ ) {
    Serial.print (Robot.IRarray [i] ) ; // print the values to the serial port
    Serial.print ( "," ) ;
  }
  Serial.println ( "" ) ;
  delay ( 100 ) ;
}
