Hello everyone, to start yes i know this post has been asked many times before but i hope to get a more up to date answer to the question and hopefully something i do not have to create myself.
I have been creating a environmental control system which i started as just a fun idea but now i have quite a few subscribers and as a result requests for more features, one of those being AC dual fan speed control to maintain the air temperature and humidity. The code is not an issue and in fact i worked on a AC fan speed controller at my last job though i did the GUI code but i have access to the fan logic which works perfectly.
My question is, is there a AC fan - motor controller which operates via a 5v PWM signal that i can just buy rather than having to create a custom PCB? Else if i must create it myself could anyone recommend a good example - tutorial on how to create one, I really dont want to have to create my own as it would take time and money but if i must then so be it.
I found a simple one already but from what i can tell it is not PWM controlled and rather just fixed output?

Sorry to rant on and i hope you can help me,
