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.<br /> <br /> <br /> &#039;&#039;&#039;connecting to arduino&#039;&#039;&#039;<br /> <br /> After following the instructions in the producer website, I have managed to get the first digital outputs from the sensor.<br /> <br /> &lt;gallery&gt;<br /> File:sel_digital1.JPG<br /> File:sel_digitalserial.png<br /> File:sel_analog2.JPG<br /> File:sel_analog3.JPG<br /> &lt;/gallery&gt;<br /> <br /> <br /> <br /> To get different numbers from the sensor(other than hi/lo), I connected it to an analog input. <br /> &lt;source style=&quot;border:none; height:auto; overflow:scroll;&quot; lang=&quot;c&quot; line start=&quot;55&quot; highlight=&quot;4&quot;&gt;<br /> void setup()<br /> {<br /> Serial.begin(9600);<br /> }<br /> void loop()<br /> {<br /> <br /> <br /> Serial.println(analogRead(A0)); // print the data from the sensor<br /> <br /> <br /> delay(500);<br /> }<br /> &lt;/source&gt;<br /> <br /> &lt;gallery&gt;<br /> File:sel_analog1.JPG<br /> File:Screen Shot 2022-11-30 at 22.15.41.png<br /> &lt;/gallery&gt;<br /> <br /> <br /> &#039;&#039;&#039;moving data to processing&#039;&#039;&#039;<br /> <br /> Following this tutorial &gt; https://www.arduino.cc/education/visualization-with-arduino-and-processing <br /> I have first uploaded this code snippet to the arduino <br /> <br /> &lt;source style=&quot;border:none; height:auto; overflow:scroll;&quot; lang=&quot;c&quot; line start=&quot;55&quot; highlight=&quot;4&quot;&gt;<br /> unsigned int ADCValue;<br /> void setup(){<br /> Serial.begin(9600);<br /> }<br /> <br /> void loop(){<br /> <br /> int val = analogRead(0);<br /> val = map(val, 0, 300, 0, 255);<br /> Serial.println(val);<br /> delay(50);<br /> }<br /> &lt;/source&gt;<br /> <br /> Lastly running different examples from the same tutorial on processing, resulted in different visualization of the black/white data retrieved from the sensor.<br /> <br /> [[File:sel_processing.mp4]]</div>
