Great video. A challenging question: what could the PWM output of an STM be used for? Well of course, possibly 3/4 of the applications that STMs are used for, use PWM. The problem comes when one needs to find demonstration applications. One doesn't want to propose applications that need a workshop full of components; nor does one want to risk losing the viewers interest with applications that employ technologies that have not yet been addressed by the channel. So, how about a temperature controlled fan? The goal would be not just energy saving but noise reduction. That latter aspect does reveal one of the challenges that comes with the use of PWM: electric motors can get noisier when their power supply is interrupted at audible frequencies.
You are absolutely correct. There are thousands of applications, and I did provide an application hint in this one where the PWM can control a hobby servo, but there are applications like motor control, spindle/vfd control, laser intensity, etc. If the device has a PWM input, it can be used.
Great video, just as all the others from you that I've watched! Nevertheless I would also like to know, why you don't like turning down the voltage right down to 0V? Your videos really help me a lot! :-)
Yes, I think so because it is very easy and interesting, one of a better way to publish courses. I hope your new courses in there soon (sorry for my bad English) thank you for the reply
I appreciate the feedback. I did consider Udemy a few months ago, but didn't really think it was a good way to pay for the time involved in making the videos. I will reconsider this. Thanks.

I like the lecture and keep it up.
Thank you, I will
great . we need vids like this about stm32 + nokia 5110 lcd . please. keep it up.
Thanks.

Thanks for the kind workds. I don't have a resistor on each lead of the trimmer and I don't want to bring a pin all the way to 3.3v or 0v.
Hi, and thank you so much for the work. Any paypal account we can donate to?
Could you make some courses on UDEMY about microcontroller programming and hardware development.....???
Thanks Chathura, Do you believe that Udemy has a better way to access the tutorials?

OK thanks..!!
