This video is a collaboration with Detlef from Det Builds Stuff and sponsored by PCBWay. We look at a recent project we built from the shared projects section and try to replicate this device with a microcontroller based version. Hopefully this will reduce the component count and cost, and may even work better too. Here is a mostly unedited design and proof of concept session captured on video. Let's see if it works. This video describes the hardware development for the project, For those interested in exploring the software side then follow this link to the companion video on Detlef's channel
