Best & Fast Prototype ($2 for 10 PCBs): www.jlcpcb.com
Thanks to JLCPCB for supporting this video.
I show you with more details how the ultrasonic distance sensor works. Then, using that theory, we create our own module, we amplify and send a 40KHz pulse, we receive the bounced wave, amplify it and then create the code. I hope that you will learn something new with this project.
