Hi There
Here is the link for the online Arduino simulation for the ultrasonic sensor example you have provided.
Link: https://wokwi.com/arduino/projects/290962720810861064
This is a permanent link.
My request is:
can I create a PR to add this link to the ReadMe file so that all the users of this library can get a hands-on experience and confidence before they download the library or buy the hardware? Please give your feedback!

Thank you
Puneeth
