ESP32 Radar System
I can't think of a single use case for the resulting project. But this is a great project
I follow several feeds on YouTube on the topics of logic controllers, SBC's, PCB fabrication and modern microcontrollers. Most would find the topics boring, but that's me. So a few days ago I watched a video because the thumbnail caught my eye. Now of course it is not real radar, but it looks the part.
So the used an ESP32 (cost about $4) and an ultrasonic distance sensor (cost $2), so it's literally a $6 project! He built a distance sensor that looks like radar. Super impressive idea.
Now honestly, I can't think of a single use case for the resulting project. But this is a great project to learn how to build with Arduino , ESP32 or any other micro-controller. Plus the end result looks pretty cool visually. The video link is here, if you wanna check it out. It's worth the watch.
