How to make piezo disc vibrate as output

[omri_bergman]

hey,
I have a piezo disc (20 mm), can I make it vibrate as an output from my Arduino?

thanks

You can attach it to an Arduino output and call tone( ).

OR

thank you
the piezo makes sounds but doesn't vibrate (that I can feel), you know how to do that?

What makes you think it can vibrate in that way?

Here is a vibrator: https://fr.aliexpress.com/item/1005001739998295.html

Not all piezo are equal, some are designed as sounders but low-power. Other industrial strength units like used in an ultrasonic cleaner consume a significant amount of power and can even weld steel.

It does vibrate, but you may not notice it. The small piezo disks used for alarms and buzzers are designed to have a significant response only over a limited frequency range, usually tones between about 2 and 4 kHz.
