<h3 id="pcb-design">PCB Design</h3>
<p>I have started designing my circuit board using the kokopelli software. After I had finished designing the circuit board, Mr. Fransisco recommended me to reduce the size of the circuit board because there were many empty parts within the designed circuit board, and he told me that the small circuit boards are more attractive for people.</p>
<p>In order to design the circuit board I have copied the code text where all the components are defined from this <a href="https://pub.pages.cba.mit.edu/libraries/kokompe/pcb.cad">link</a>. Then I started writing my own code text for designing in <strong>define board</strong> section. The text for my circuit design was as follow:</p>
<p>``` # define board #</p>
