I'm a beginner at arduino. For a project I want to create standing ultrasound waves and be able to change the frequency. The circuit also has to be waterproof.
I have these two items JSN-SR04T Ultrasonic Distance Measuring Sensor - Waterproof and Weather-proof Ultrasonic Sensor (SEN0207).
- I'm also trying to follow this tutorial ULTRASONIC LEVITATION Machine Using ARDUINO - Arduino Project Hub although I have different parts as you can see. How should I go about this? How do I learn what wire goes into what and what pieces I need? How can I control and change the frequency emitted?
