Low frequency oscillators for Node-RED
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
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:
Beware of setting the sampling rate too low as it may hog your CPU.
