Arduino

Open-source electronics platform

Arduino is an open-source electronics platform combining simple hardware and software, used for building interactive projects.

The microcontroller boards read inputs—light sensors, button presses—and turn them into outputs like activating motors or triggering displays.

Arduino democratized physical computing, making it accessible to hobbyists, artists, and students without electrical engineering backgrounds: I built a weather station with an Arduino.
