Featured Build
Smart Home
Build a scaled-down smart home model that combines sensors, status indicators, and an automated entry barrier into one coordinated system.

The guide is in review. It opens here once a reviewer has checked the build.
How it works
Sensing
The sensors report what is happening in different parts of the model.
Processing
Your code reads those inputs and keeps track of the system's current state.
Control
The LEDs and automated barrier respond based on what the sensors detect.
System
All of the sensing, logic, and outputs run together continuously as one coordinated smart-home system.
Peer-Verified Standard
Projects you can actually rebuild.
Every guide is written by the student who built it and checked against the real hardware before publication. Free to read, no account required.
Every published guide includes
- Real photos of the working build, with wiring that matches it
- Exact parts, versions, and complete, tested code
- Observed results and known limits, checked by a reviewer
