Sensai

Arduino App Lab — the unified editor for the Uno Q that builds and runs projects on both the MPU and MCU at once. Read this when the user asks about App Lab, Bricks, Apps, deploying a project, "Run" button workflow, or how Python+sketch projects are structured. Sensai itself is a Sensai-customized alternative entry point, but understanding App Lab is essential context.

Arduino Bridge — software RPC layer that connects Python on the MPU (Linux side) with Arduino sketches on the MCU (STM32U585). Read this BEFORE writing any project that combines a Python program with an Arduino sketch, or that asks "how do I send data from my sketch to the Linux side?". The Uno Q is two processors on one board; Bridge is how they talk.

Arduino Uno Q built-in 12x8 LED matrix — scroll text, draw frames, play animations using Arduino_LED_Matrix + ArduinoGraphics libraries (bundled with arduino:zephyr core). Read this before writing any sketch that mentions the LED matrix, scrolling text, or drawing pixels.

Linux sysfs LED control — drive the Uno Q's MPU-side RGB LEDs (RGB LED 1 and RGB LED 2) from Python with no sketch involvement. Read this when the user wants to blink or color a board LED using only Python on the Linux side, or asks about the SoC LEDs / panic LED / WLAN LED / Bluetooth LED. The MCU-side RGB LEDs (LED 3 and LED 4) use a sketch instead — see `sketch-patterns/SKILL.md`.

Canonical Arduino sketch templates for Uno Q — scaffold, breathing/fading LED (analogWrite for-loops), blink, button with INPUT_PULLUP, potentiometer analogRead, Servo sweep. Read this before writing any .ino sketch.

Arduino Uno Q board pinout and voltage rules — JDIGITAL/JANALOG/Qwiic/JSPI pin tables, PWM pins, 3.3V ADC limits, MPU vs MCU split. Read this before answering any question that names a pin (D0–D21, A0–A5) or voltage.

Wi-Fi and Bluetooth on the Uno Q — the WCN3980 module exposes dual-band Wi-Fi 5 (802.11a/b/g/n/ac) and Bluetooth 5.1 to the Linux MPU side. Read this BEFORE writing any project that says "connect to Wi-Fi", "send over the network", "HTTP request", "Bluetooth", or "send my sensor data to my phone". The wireless module is owned by Linux — sketches reach the network via Bridge.
