Hi. I am making a smart home prototype where I connected the door with Servo-motor and I wanna rotate the motor on one fix position (95°) then it can open my door. Now I switch from the dashboard and connect it with GPIO out (PWM) with frequency 100 Hz and it is rotating 180°. I think I need to add …

Well, I am not sure what values I need to assign and where I need to assign for Servo. But physically, I need 0 to 95°.

Slight aside - the pi-gpiod node https://flows.nodered.org/node/node-red-node-pi-gpiod - provides much better timing accuracy for servo positioning (for normal RC model servos), but does need some more setting up.

One other thing to keep in mind, a servo motor can usually only turn 90 degrees in either direction for a total of 180 degree movement. Therefore you will probably have to set it up so home as -45 and open as 50 to get your 95 degree swing.

Thanks for your reply, I didn`t get your point how I can set the home and where I need to set 50 degree

First find the range of numbers that gives you the angles you need. Next what signal or input are you using to decide what position you want it set to?

I am using range and GPIO out nodes but it is not work: [{"id":"8777601e.137e5","type":"range","z":"675ddecd.d7a01","minin":"0","maxin":"100","minout":"100","maxout":"0","action":"scale","round":false,"property":"payload","name":"","x":380,"y":300,"wires":[["d11fc2.f6d1204"]]},{"id":"d11fc2.f6d1204…

Please read this link and edit your previous post so that we can import the flow. Also tell us what about it does not work. [image] How to share code or flow json FAQs To share code samples or flow json in this forum, you need to take care to format it properly so that it…

And what does not work? Your flow only has the the nodes to inject one value (1).

Actually, I mounted Servo motor with smart home door and wanna to open and close the door with servo movement.

So if you put different values in inject nodes are you able to make it move the right points?

Different values in inject node means. Yes, I know I can add 0 to 9 as mention payload number.
