<h3>Arduino Serial Plotter to Compare Analog and digital signals</h3>
<p>To understand how the signals are correlated I use one of my capacitive touch sensors, (you can see more <a href="http://fabacademy.org/2021/labs/zoi/students/ismael-larrea/assignments/input-devices.html#fabrication" target="_blank" rel="noopener noreferrer">here</a>) and program the microprocessor to send via serial port the row value and a 'digital' that is compared with a threshold value.</p>

<p>As you can see using a threshold value you can make digital sensor output when you need only a true false reading.</p>
