+Line tracking sensor can be used to differentiate between black and white with the integrated infrared sensors(one emitting, one collecting). It is very dependent on the reflectiveness of the material/object therefore it is important to have a consistent and equal light source on the surface.

-To get different numbers from the sensor(other than hi/lo), I connected it to an analog input.

+Following this tutorial > https://www.arduino.cc/education/visualization-with-arduino-and-processing
+I have first uploaded this code snippet to the arduino
+<source style="border:none; height:auto; overflow:scroll;" lang="c" line start="55" highlight="4">
+unsigned int ADCValue;
+void setup(){
+    Serial.begin(9600);
+}
+void loop(){
+ int val = analogRead(0);
+   val = map(val, 0, 300, 0, 255);
+    Serial.println(val);
+delay(50);
+}
+</source>
+Lastly running different examples from the same tutorial on processing, resulted in different visualization of the black/white data retrieved from the sensor.
