Real hardware. Real documentation.
Studio Pieters documents ESP32 boards, Apple HomeKit builds, and the electronics behind them, verified against the datasheet, not against a guess.
What this is
A pinout, a wiring diagram, and a build guide, for the boards and components that actually get used: ESP32 in its many variants, Arduino, ATtiny, and the sensors and drivers that go around them. Every dimension drawing traces back to a real datasheet. Every guide exists because a real project needed it.
Why it exists
Searching for a pinout usually means piecing it together from a forum thread, a blurry photo, and a datasheet PDF that was never meant for casual reading. Studio Pieters puts the pin numbers, the voltages, and the wiring in one place, checked against the source, so the next hour is spent building, not verifying.
Where HomeKit fits in
A recurring thread through the projects here: an ESP32 board, talking to Apple Home, without a cloud service in between. The HomeKit guides cover exactly that, from first pairing to a finished accessory.
