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.
Lawn Sprinkler Controller
Turn an Olimex ESP32-C6-EVB and its four onboard relays into a Wi-Fi sprinkler timer with per-zone control, a manual run, and a weekly schedule — all served from a browser page you generate, not hand-code.
Playing Piano
Who says MIDI has to be mysterious? Build a fun web-based control panel for the Seeed XIAO MIDI Synthesizer, turning a tiny microcontroller into a surprisingly capable musical instrument. Create an interface that lets you shape sounds in real time. See how easy it can be to bring hardware and music together.
