Wave

Wave

The Wave node outputs a continuous Wave that oscillates (swings back and forth). There are a number of different Waveforms (types of waves) that can be selected. The Wave Node can be used in many different situations like moving a Servo Motor back and forth, blinking an LED or iterating trough a List.

Connections

Inputs

  • length
    • Range: 0 - 1000
    • Length of the period of the Waveform in seconds.
  • type
    • Values: WAVE_SINE, WAVE_SQUARE, WAVE_TRIANGLE, WAVE_PULSE, WAVE_RAMP_UP, WAVE_RAMP_DOWN
    • The type of Waveform.
  • min
    • Range: 0 - 1
    • Trough value (the lowest) of the Wave.
  • max
    • Range: 0 - 1
    • Peak value (the highest) of the Wave.
  • offset
    • Range: 0 - 1
    • Offset of the period of the Waveform.

Outputs

  • out
    • Range: min - max
    • A continuous Wave oscillating between the min and max values.

Comment

You can put a Wave into a Wave by connecting the output of one wave to the length input. This is called modulation and can create some very interesting results.

Waves are fun and interesting! And the world in full of them. Kahn Academy has some good material on Waves.
