Arduino Uno R4 WiFi LESSON 52: HC-SR04 Ultrasonic Distance Sensor Project

[@johnrw4517]

I wish I had you for a math teacher back in school. You stress the fundamentals of learning Math and not just a quick solution with no explanation. Thank you!

Happy to help!

Thanks!

Thanks, I really appreciate the support!

I took the ultrasonic sensor project to the outdoors. I put one in my rain barrel so that when it got to a low level it would not let the rain barrel pump come on and also let me know how much water is inside the barrel. Works great! The outdoor sensor is the HiLetgo JSN-SR04T Integrated Ultrasonic Transducer Sensor Waterproof, Amazon of course. Two in the package for $17USD. Another GREAT video

Do you measure the time from the puls get hi or from the pulse gets low.?

[@arnoldschmucker9977]

I seem to recall a video in which you showed us a method of overwriting a line of output to keep the serial monitor stationary. I can't find the video. Do you remember any such videos?

[@paulmcwhorter]

I am not sure what lesson that was.

[@ominence5573]

I have a lot of catch up to do, ive missed videos since lesson 15. Im back on it! All the best for 2025!

[@paulmcwhorter]

Independent Study: Arduino Ultrasonic Theremin kzbin.info/www/bejne/Y5WwdHqqrJyWfdEsi=GVM2sG1xb-0J4laM Used pingTime as frequency to drive DAC(A0) pin. Audio played through computer audio interface. Tried using passive buzzer but sound level was barely audible.
