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...

Arduino Inventor’s Guide CIRC-02 (Multiple LEDs)

The second circuit in the Arduino Inventor’s Guide is a little more complicated than the first one. This time there are 8 LEDs connected to the board, but the LED animation is still fairly simple. It iterates over each LED and turns each one on. Once they are all on, it then loops backward turning each one off. It uses: Arduino CIRC-02 1 x Arduino Duemilanove 1 x breadboard 8 x Yellow LED 8 x 330 Ohm resistor...
