All tutorials on ESP32 Engine are provided for educational and informational purposes only.

Electronics projects involve risk. Always verify wiring, use appropriate power supplies, and follow safety guidelines when working with mains voltage, motors, pumps, relays, or high-current loads.

Healthcare projects: Tutorials in the Healthcare category are not medical advice and must not be used for diagnosis, treatment, or patient monitoring.

Battery and power warning: Li-ion batteries, motors, servos, pumps, LED strips, and relay-controlled loads can draw more current than an ESP32 USB port can safely supply. Use appropriate power supplies, fuses, isolation, and adult or qualified supervision.

Code samples are starting points. You are responsible for testing and adapting firmware for your exact hardware and use case. See our Testing Methodology and Editorial Policy for how tutorials are prepared.
