Pick your Sunfounder kit up so you get the same results I do:

You can get the oscilloscope like I use in this lesson. Note, you do not have to have an oscilloscope to complete this class, but it is helpful in troubleshooting your circuits:

You guys can help me out over at Patreon, and that will help me keep my gear updated, and help me keep this quality content coming:

In this video we will learn how to use echolocation in our arduino projects. Echolocation is how bats can fly in the dark. They create a chirp, and then listen for the chirp to reflect off an object. It can then perceive how far the object is away. Similarly, submarines know how far obstructions are away by using Sonar. The submarine sends out an audible ping, and then listens for the return of the ping. For our Arduino, we have a HC-SR04 Ultrasonic sensor which will act like a Sonar. It creates a ping, and then listens for the ping to return. This is useful in robotics so your project can know how far it is from a wall or other object, so it will not run into things. In this lesson we will hook the sensor up, and show how to make measurements. Enjoy!

Note that the link in the notes for this lesson to the Aiteme oscilloscope on Amazon says that it is currenly unavailable and Amazon doesn't know when or if it will be back in stock. Do you have a preferred alternative?

@@paulmcwhorter Thanks. When I went to that page again, it said 7 were available. I ordered 1 and when I finished checking out it said 10 were available. They must have just had a shipment come in.

Is this how I could light up a LED strip in my garage to tell how far my car is from the wall?

That should be doable. Sounds like a great project.

Could you please change you IDE screen to black to make it a little easier to read and follow the code. Even on my 32 inch monitor it is all most imposable for me to read. Thank you .

Try increasing the video quality; Paul’s videos are HD. On the right side of the video’s timeline, just below it, is a little gearwheel; select it. The Quality is probably set too low. Set it to 1080P60 HD. It will probably give you a better viewing experience. However, increased bandwidth will require your PC to work a little harder.
