Arduino boards run sketches in C-like Wiring on AVR microcontrollers — blink LEDs, read sensors, drive motors with a USBUniversal Serial Bus — a standard connector and protocol for peripherals and devices. cable and no OSOperating system — software that manages hardware and provides services to applications.. Makers, educators, and IoTInternet of Things — networked sensors and devices embedded in appliances, factories, and cities. prototypes used it before Raspberry Pi brought full Linux to the same audience. The IDEIntegrated development environment — an editor with debugging, build tools, and project management built in. and shield ecosystem made embedded programming accessible without a EE degree.

Arduino democratized microcontroller programming for non-specialists.

It launched the modern maker movement and influenced IoTInternet of Things — networked sensors and devices embedded in appliances, factories, and cities. prototyping worldwide.
