A Real Dual-Brain Application on the Arduino UNO Q: an AI Brick, a Camera, and a Presence Lamp

Part two of the UNO Q series puts the board's dual-brain design to real work - a vision AI Brick on the Linux side detects a person through a camera, and the microcontroller side turns that into a smoothly breathing lamp that never stutters, no matter how hard the AI is working.

Getting to Know the Arduino UNO Q: Two Brains, One Board, and Zephyr Underneath

The Arduino UNO Q pairs a quad-core Linux processor with a real-time STM32 microcontroller on one UNO-shaped board, and quietly runs Zephyr where the classic Arduino runtime used to be. This guide takes an engineer's look at the architecture.

The Zephyr Web Server, Now in C++: Classes for Embedded Hardware

A short follow-on from the Zephyr Thread web server guide, rebuilding the same project in C++ on the Seeed XIAO nRF52840, and adding the RGB LED and the on-die temperature sensor to show why classes suit Zephyr hardware so well.

A Zephyr Web Server on the Seeed XIAO nRF52840, over Thread (C/C++)

In an earlier guide we built a tiny web server on an ESP32-C3 in async Rust, using Embassy. A browser could connect over Wi-Fi,
