readColorRgb(id)

Get the RGB value of color sensor.

Parameter

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

Return Values

Parameters	Type	Description
array	unsigned char *	Return an RGB array. The first is the R value, the second is the G value and the third is B value

Example

Use the uKit Explore v2 board to display the RGB value read from color sensor every 400ms.

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

void loop() {    
    unsigned char *rgbValues=NULL;    
    rgbValues=readColorRgb(1);    
    Serial.println("R value:");    
    Serial.println(rgbValues[0]);    
    Serial.println(",G value:");    
    Serial.println(rgbValues[1]);    
    Serial.println(",B value:");    
    Serial.println(rgbValues[2]);    
    delay(400);
}

Use the uKit Explore v2 on-board RGB LED to show the color read by the color sensor.

#include "uKitExplore2.h"
unsigned char *rgbValues=NULL;
void setup() {    
    Initialization();
}

void loop() {    
    rgbValues=readColorRgb(1);    
    setRgbledColor(rgbValues[0],rgbValues[1],rgbValues[2]);   
    delay(100);
}
