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);
}
