8 x RGB LED Array

Using Arduino LEDs and Multiplexing
20

I still cannot grasp exactly what your trying to do with the value you get but if your trying to turn on/off the LED's in the binary pattern corresponding to the value receive then you can also do it this way

const byte target = B11110001;

void setup(){
    Serial.begin(9600);
}

void loop(){
    for (byte x=0;x<8;x++){
        if (((target>>x) & 1)==1){
            Serial.print("1");
        }
        else {
            Serial.print("0");
        }
    }
             Serial.println();

    for (byte x=0;x<8;x++){
        if (((target<<x) & 128)==128){
            Serial.print("1");
        }
        else {
            Serial.print("0");
        }
    }
    while(true){
    }
}

I have included 2x versions that rotate the bits out to either the left or the right.
