Buzz click explained.
The excellent blogging team from Italy is back with a detailed treatment of Buzz click. How piezoelectricity works. Why buzzers buzz when an AC voltage is applied. Which frequencies get the best resonant response, and finally, a ChibiOS/HAL demo.
We are happy to see the blog itself getting a buzz, with a dozen social media shares for each of their posts.
If you like their work, you can buy them a beer (check the bottom of each post).
Yours sincerely,
