want to produce a 2 tone sound (2khz-6khz) (see deer chaser post) but am lost as a piezo will produce set frequency (internal drive) when voltage is applied.Can a piezo produce variable frequencies?
looking at maybe a VCO to produce the 2-6khz frequencies?
at what frequency is ultrasonic?? or is there really a definite frequency?
This device will be outside thus weather proof.
