Hi,
Thanks for taking the time out to read this post.
My question is, what value resistor should I use to drive my 3Vp-p piezo buzzer (Multicomp MCABT-401 RC)?
Here's the datasheet.
I've been browsing the web for various examples, and came across many examples like the one here.
As you can see from the image in the link, the piezo is driven by a PWM via 1k resistor.
This example uses a 1k resistor with a 5V supply. Should I use a different value resistor because mine is being driven by 3V? (I'm using a PIC32MX795F512L - datasheet).
How would you go about calculating an adequate resistor value for Piezo Buzzer?
Many thanks,
Rob
