Build a LoRa sensor network that reaches kilometers on a couple of AA batteries — full parts list, wiring schematic, sensor node and gateway code, and real-world range tuning.
Build an ESP32-CAM security camera that filters false alarms with on-device AI detection — full code, wiring schematic, PIR motion trigger, and a path to real object classification.
Build an ESP32 predictive maintenance system that catches motor failures before they happen — vibration + current sensing, anomaly detection code, full wiring schematic, and a path to real TinyML.
ESP32 is quietly going through its biggest shake-up since 2016 — RISC-V chips, Wi-Fi 6E, Matter/Thread support, and ESP-IDF overtaking Arduino for production firmware. Here’s what it means for your next project.
