readInfraredDistance(id)

Get infrared sensor distance value.

Parameter

Parameters	Type	Description
id	unsigned char	ID number to be controlled, range 0 ~ 10

Return Values

Parameters	Type	Description
number	int	Distance, range 0 ~ 20cm

Example

Use the uKit Explore v2 board to display the distance read by infrared sensor ID-1 every 400ms

#include "uKitExplore2.h"
void setup() {    
    Initialization();
}

void loop() {    
    Serial.println(readInfraredDistance(1));    
    delay(400);
}

Use the uKit Explore v2 board to read the infrared sensor distance. When the distance is less than 5cm, set the on-board LED to RED, and when the distance is more than 5cm, set the on-board LED to GREEN.

#include "uKitExplore2.h"
volatile int item;

void setup() {    
    Initialization();     
    item = 0;
}

void loop() {    
    item=readInfraredDistance(1));    
    if(item>0 && item<5){        
        setRgbledColor(255,0,0);        
        delay(300);      
    }    
    else{        
        setRgbledColor(0,255,0);        
        delay(300);          
    }
}
