Tutorial: Use analogWrite to vary speeds of fans

Tutorial: Learn how to use your Arduino, Teensys or ESP32's to write analog signals for varying the brightness of an LED or controlling the speed of a fan using PWM or pulsed width modulation. In this tutorial you will learn the commands, and see how to implement analogWrite.

Thanks, good job!

[@KrisKasprzak]

Glad it helped!

Nice video. I see that you use EasyEDA. How do you like it, and have you any thoughts on KiCAD?

[@KrisKasprzak]

I've never used KiCAD, but I'm fairly well versed with EasyEDA
+
huge library, mainly from the community
fairly easy to use software
easy way to get from schematic to routing
pretty reliable router, download the router for local use
simple to get a design done, and then purchase
Fast easy to get professional results
Can export a DXF for importing into 3D CAD for making perfect-fit cases
-
horrible ability to keep things connected on the schematic, if you move a component expect connected paths to disconnect
can't store files locally, I suspect you can get the gerber files though
library authoring is a bit clunky, but usable
wishlist
have an integrated circuit analysis tool--to minimize breadboard stuff

@@KrisKasprzak Thanks so much for the detailed reply. Very helpful. I did download the router and noticed the paths disconnecting!
Also, searched for Schmitt trigger and only got one result. Searched for 74CH14, got numerous results.
