An enhancement to my recent pond pump project - pump speed control! ► PCBWay $5 for 10 pieces https://www.pcbway.com 5th PCB Design Contest underway right now! Check it out! ► More info in my GitHub: https://github.com/RalphBacon/255-Che... Having installed a pond pump there came the inevitable "upgrade" request: "Can we make the pump more controllable?". Well YES, we can, as it happens. Products Any PWM controller will adjust the speed of a motor like this. But I couldn't face building one, so I bought a cheap one off the Internet (Amazon UK, actually): https://amzn.to/3Be0Z8p You can get them cheaper if you are prepared to wait for a while, see this one from AliExpress: https://s.click.aliexpress.com/e/_DBf... Identical products (apparently), just a different price. Pays your money, takes your choice. I found a video on YouTube by @RJ Imagination that demonstrates the same circuit (pretty much):    • PWM using OP-amp | how to make pwm us...   https://www.circuits-diy.com/pwm-puls...

A reasonable MOSFET for use by Arduino users (ie a 5v GPIO voltage) not suitable for ESP32 use (not without a level shifter): https://www.infineon.com/dgdl/irl540n... ► List of all my videos (Special thanks to Michael Kurt Vogel for compiling this) http://bit.ly/YouTubeVideoList-RalphB... ► More info in my GitHub: https://github.com/RalphBacon/255-Che... ► If you like this video please give it a thumbs up, share it and if you're not already subscribed please consider doing so and joining me on my Arduinite (and other μControllers) journey My channel, GitHub and blog are here: ------------------------------------------------------------------ •    / ralphbacon   • https://ralphbacon.blog • https://github.com/RalphBacon • https://buymeacoffee.com/ralphbacon ------------------------------------------------------------------ My ABOUT page with email address:    / ralphbacon
