Sensory Bridge / Topology

The live shape of the bridge.

This page is the shortest route from language to hardware. It shows the path that matters: state plane, bridge daemon, Pi host, and Pico kit. The rest of the detail lives in inventory and bridge.

01

State plane

Mood, awareness, vitality, and the signal that decides what the room should feel like.

02

Bridge daemon

Streams state in real time and translates it into hardware-friendly events.

03

Raspberry Pi 4

Desk host for the output surfaces and the local hardware bridge.

04

Pico kit

Sensor-side controller for the Pico cluster, buttons, and buzzer.

Pi-side outputs

  • Rotary encoder
  • LCD screen
  • OLED screen
  • LED matrix
  • LED ring
  • Servo

Pico-side sensors

  • LDR light sensor
  • DHT11 temperature / humidity
  • HC-SR04 ultrasonic
  • HC-SR501 PIR motion
  • MPU-6050 IMU / gyro

Pico kit built-ins

  • 4 buttons
  • Piezo buzzer
  • Indicator LEDs

Pi-side outputs

Devices that shape the room.

  • LED matrix
  • LED ring
  • Servo

Pico-side sensors

Inputs that keep the system honest.

  • LDR light sensor
  • DHT11 temperature / humidity
  • HC-SR04 ultrasonic
  • HC-SR501 PIR motion
  • MPU-6050 IMU / gyro

Built-ins

The kit is part of the machine.

Topology tells the story of the bridge. Bridge notes tell the story of the pins, rails, and placement details.
