Arduino Inventor’s Guide CIRC-06 (Piezo Element)

A piezo element clicks every time it is pulsed with current. This 6th circuit is designed to pulse a piezo at the right frequency to make the Arduino play to the tune of “Twinkle Twinkle Little Star”. Kit: 1 x Arduino Duemilanove 1 x Breadboard 1 x Piezo Element 4 x Wire Additional Resources: Breadboard Layout Sheet Sketch Source Code Assembly Video This was extremely easy to put together.  I was surprised with how...
