I built a simple radar + dashboard in about 40 minutes.
I had a servo motor, ultrasonic sensor, and an ESP32 sitting around, so I got curious about what I could make with them.
The setup is pretty simple: the servo sweeps the sensor, the ESP32 reads the distance, and that data is sent to a small web dashboard that visualizes it in real time.
This little experiment got me into microcontrollers a few months ago. Since then, I've built an outdoor smart pot and an autonomous robot.
I'll be sharing more of that IoT journey in the next few posts.

This is a great example of a fast hardware prototype becoming a readable interface—the radar view and live servo setup make the feedback loop tangible. The 40-minute constraint clearly kept the build focused on the core interaction.
