How do I make an rotary encoder work properly in node red? I have multiple inputs and I want to control them using an encoder, any ideias? [image]

[image] Colin: how is the encoder connected to your computer? You have not answered that question.

So the GND Is conected to GND (pin 9) The + is conected to 3.3V (Pin 1) The DT is conected to GPIO17 (pin 11) And the CLK Is conected to GPIO 18 (pin 12)

Do you have some software that allows you to determine the position, or some algorithm that has to be used to determine it? If it is designed for a pi it probably comes with some s/w.

No I dont have a software that allows that, and yes it comes with an SW but I didnt conect it to anything

I just connected the encoder to the pi, Im not using anything besides the pi, de encoder and of course the node red

Just for as an exercise - I've come up with this flow - try connecting your DT/CLK signals to the two inputs and see if it give any sensible results at all. Put CLK signal into top input [image] [{"id":"4cc4dd5a.e99f44","type":"switch","z":"dfaf687e.30fb88","name":"","property":"payload.DT","pro…
