Built-ins
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.
Why this shape works
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.
