Core device
Raspberry Pi 4
Pi-side host for the hardware stack and the local bridge to the desk surfaces.
Sensory Bridge / Inventory
What is on the desk.
A device-level inventory, intentionally pin-agnostic. This page is the one to read when you want to know what exists, what is live, and what is still deliberately left out of the map.
Core device
Raspberry Pi Pico
Sensor-side controller for the Pico cluster, buttons, and buzzer.
Core device
Pico Breadboard Kit
The all-in-one kit that holds the Pico, built-ins, and the small on-board breadboard.
Core device
Pi breadboard
The separate full-size breadboard that carries the main output-side cabling.
Pi-side outputs
Confirmed live group
- Rotary encoder
- LCD screen
- OLED screen
- LED matrix
- LED ring
- Servo
Pico-side sensors
Confirmed live group
- LDR light sensor
- DHT11 temperature / humidity
- HC-SR04 ultrasonic
- HC-SR501 PIR motion
- MPU-6050 IMU / gyro
Pico kit built-ins
Confirmed live group
- 4 buttons
- Piezo buzzer
- Indicator LEDs
Power split
Keep the sides separate.
- Pi-side outputs: 5V for servo, matrix, ring; 3V3 for the other Pi-side devices.
- Pico side: 3V3 only.
Why it matters
This is the inventory the rest of the bridge should point back to.
If a new device appears, or one of the live groups changes shape, this page should be the first thing updated. The diagram can change. The inventory is the base record.
