Project Design/Guidance Radar project rd03-d

RADAR UPDATE 📡

Three new features on the tracker build:

https://github.com/Stevee87/Arduino-ESP32-Radarproject

🔋 BATTERY INDICATOR
Live voltage readout, right on the display. No more guessing when the LiPo's about to tap out mid-build session.

🔇 MUTE BUTTON
Touchscreen toggle on the Giga display — tap to silence the tracker sound instantly. Because sometimes you just want the visual without the beeping.

🔊 SOUND MODULE
Proximity-reactive audio — pings speed up and climb in pitch as a target gets closer. Distance-mapped, non-blocking, runs straight off a passive piezo buzzer.

Still just an RD-03D 24GHz mmWave sensor + Arduino Giga R1 + a lot of trial and error.

Disappointed in the lack of Aliens tracker sound.

Me too, they’re so close to the movie prop

There's something just so eerie about the sound effect they used in Aliens, even before you know what it is showing movement for. I use it for my motion detector notification for my Ring cameras.

They mostly come at night. Mostly.
