Wave

In a wave is a propagating dynamic disturbance of one or more quantities, sometimes as described by a wave equation. In physical waves, at least two field quantities in the wave medium are involved. Sound waves are variations of the local pressure and particle motion that propagate through the medium.

Sine Wave

To the human ear, a sound that is made of more than one sine wave will have perceptible harmonics, addition of different sine waves results in a different waveform and thus changes the timbre of the sound. Presence of higher harmonics in addition to the fundamental causes variation in the timbre, which is the reason why the same musical note played on different instruments sounds different.

Rotary Switch – SparkFun Rotary Switch Breakout

This is a single pole, 10 position rotary switch able to select up to 10 different states in a durable package. Unlike our other rotary switch, this model is much more robust and capable of handling larger currents and voltages. Though this switch requires you to use 11 pins and is not breadboard friendly we do offer a breakout board to provide easier access to its capabilities.

This is the SparkFun Rotary Switch Breakout, a very simple board designed to easily provide you access to each pin on our 10-position rotary switches. This breakout allows you to easily add a rotary switch to your next project without having to worry about attaching its unique footprint to a custom board or solderless breadboard. All you need to do is solder the 10-position rotary switch into the breakout and each pin will become available for breadboard or hookup wire compatibility.
