The other lead of the capacitor connects to the second Piezo element lead. You won&amp;#39;t get huge power out of it - the element can only flex a little bit without cracking and each flex produces just a little charge which ends up on the capacitor. Since the element only generates a small amount of charge on each flex, to get a lot of charge, requires the element to be rapidly flexed. You can see a demonstration of me vibrating an element like this with an old oscillating razor to produce enough current to illuminate a couple of LEDs. They will generate pretty high voltages if there is no load.&lt;/p&gt;&lt;p&gt;&lt;a class="jive-link-blog-small" href="/products/arduino/b/blog/posts/tis-the-season-for-arduino"&gt;Tis The Season For Arduino&lt;/a&gt;&lt;/p&gt;&lt;img src="https://community.element14.com/aggbug?PostID=19990&amp;AppID=293&amp;AppType=Weblog&amp;ContentType=0" width="1" height="1"&gt;</description></item></channel></rss>
