Hey there,
I need some help with making some decisions for a little project i like to do.
I like to use as many piezos as possible (10 to 50) as kind of speakers for low quality sinus style sounds.
I know arduino has quite limited audio playing capabilities but I dont need good quality so maybe PWM is enough.
My main goal is to play different oscillators on every different piezo in a frequency range from about 5000hz to 15000hz.
Do you think I can use shift register circuit for this?
Or is it better to build small oscillators with op amps for my needs?
Sorry, for asking so dumb. I am a bit lost.
