8 March 2024: Another new attempt to control a fan (using pulsewidthmodulation). Checking the control signal by using an LED. As a result of this, I may have to consider going into a very different direction for a solution by using a relay. But I like my idea better. Click the image to watch the video. See also the blog.

29 December 2023: A new attempt to control a fan (using pulsewidthmodulation). First an old mistake is made, then some rewiring to see if electronics does the job and finally a check with other electronics to check the software. Click the image to watch the video. See also the blog.
