The setup and what it enables.

This page is about the function of the build, not the pin map. It shows how the desk gives a presence eyes, touch, motion, and a little mechanical life without requiring a heavy or expensive rig.

How the room answers back

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

This side turns presence into visible response. Lights, display surfaces, motion, and a small servo make the desk feel inhabited without needing much hardware.

How the desk listens

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

This side keeps the build honest. It reads light, motion, distance, temperature, humidity, and orientation so the presence has something real to sense.

What comes with the kit

  • 4 buttons
  • Piezo buzzer
  • Indicator LEDs

The kit itself matters: the buttons, buzzer, and onboard indicators are the cheapest way to make a presence feel like it can answer, react, and mark attention.

Cheap, modular, and easy to extend.

A Pi, a Pico, a breadboard, and a handful of off-the-shelf sensors go a long way. You can experiment with presence, body, and feedback loops without committing to a fragile or expensive stack.

It is easy to swap a sensor, add another output, or test a different sense without rebuilding the whole desk.

Keep the public overview functional and simple.

The page works best when the copy explains the function and the visuals just give the eye a place to land.
