Special Projects

Ambitious multi-component ESP32 builds that combine many sensors, actuators, and techniques

These projects go beyond single-sensor builds. Each one combines multiple components, communication protocols, and techniques into a complete, ambitious system. They are best attempted after you are comfortable with the basics from the Getting Started section and have worked with individual sensors and actuators.
