Could you build this?
No Developing firmware for an ESP32-S3 microcontroller to interface with a 24 GHz millimeter-wave radar sensor via UART and drive an RLCD display requires specialized embedded systems and hardware debugging skills.
What it would actually take: The project requires C++/C firmware built on ESP-IDF or Arduino to communicate with the HLK-LD2450 mmWave sensor over serial UART protocol and parse raw coordinate packets. The hard parts involve low-level embedded hardware interfacing, custom display timing and memory management for reflective LCD (RLCD) controllers, and real-time polar-to-Cartesian radar plotting under constrained microcontroller RAM. This requires embedded systems engineering, hardware lab equipment (logic analyzer/oscilloscope), and specialized sensor datasheet comprehension.
