@mschaeffler/node-red-pwm 0.2.1
nodes for handling of PWM.
@mschaeffler/node-red-pwm
Nodes for PWM handling in Node-Red.
If the msg property invalid is present in the message, all nodes ignore the message.
Install
$ npm install @mschaeffler/node-red-pwm
PWM input
Measures the duty cycle of a rectangular wave.
Input
The message property to be used as payload can be defined with the Property property.
