ultrsonic transducer with built in driver
« on: December 28, 2018, 08:47:35 pm »
Are ultrasonic transducers available with built in circuitry so that only need a DC voltage is needed to operate it?

How do I consider safety/ear damage, when using one?

What would be the best way to have an ultrasonic output with variable frequency?
