Build Guides

Real ESP32 projects, wired up
and brought online.

Step-by-step guides that take a real development board — relays, motors, sensors and all — and walk you through wiring the hardware and generating its web interface with ESP-GenUI. Pick a project and build along.

Something not working? The troubleshooting notes cover the ESP32 failures that give you nothing to work with — silent boot loops, flash and PSRAM mismatches, and USB cameras that never deliver a frame.
