Omar SobhandClaude Opus 4.8 8ce8474d33 feat(uno-q): wire i2c_scan into the relay, allowlist, and modulino skill
- matrix-relay/relay.py: handle the `i2c` command → Bridge.call("i2c_scan").
- config.template: allow + auto-approve i2c_scan on the default risk profile.
- modulino skill: point "confirm a module is present" at i2c_scan (MCU Qwiic
  bus) instead of the Linux i2cdetect.

Completes the container-native path: the three canned prompts (list I2C /
matrix pattern / scroll text) all run through the RouterBridge responder —
no /dev/i2c, no flash — so they work in the App Lab container node.

modulino Plug-and-play Modulino sensors/actuators for the Arduino Uno Q — Qwiic I²C modules (Buzzer, Distance, Knob, Movement, Pixels, Thermo, Touch) and their I²C addresses. Load this when a project uses a Modulino, the Qwiic connector, or asks about a named sensor module.

Modulino — Qwiic Plug-and-Play I²C

Modulinos are Arduino's Qwiic (I²C) plug-and-play modules. Chain them into the Uno Q's Qwiic connector (I2C4) — no soldering, no pull-ups to add. Use the Modulino Arduino library on the MCU, or scan the bus with the i2c_scan tool.

Default I²C addresses

Modulino Address
Buzzer 0x3C
Distance (ToF) 0x29
Knob (rotary) 0x76
Movement (IMU) 0x6A
Pixels (LEDs) 0x6C
Thermo (temp/humidity) 0x44
Touch 0x5A

Sketch pattern (MCU)

#include <Modulino.h>
ModulinoKnob knob;
void setup() { Modulino.begin(); knob.begin(); }
void loop()  { int v = knob.get(); /* ... */ }

Tips

  • Confirm a module is present with i2c_scan (scan the Qwiic/I2C bus on the MCU) — the address should match the table above.
  • Qwiic is 3.3 V, like the rest of the Arduino headers.
  • The Movement Modulino (0x6A) is an IMU — handy for the workshop's sense loop.
