Low frequency oscillators for Node-RED

npm install node-red-contrib-lfo

Low frequency oscillators for Node-RED.

Will output numbers between -1 and 1 at the given frequency according to the selected waveform.

Sending a number as msg.payload will change the frequency of the LFO. Sending the string 'stop' as msg.payload will stop the output. Sending anything else will start the waveform. The waveform can also be changed dynamically by changing msg.waveform valid choices are:

  • sine
  • saw
  • saw_i
  • triangle
  • square
  • sig

Beware of setting the sampling rate too low as it may hog your CPU.
