Arduino What is Arduino? Arduino is an open-source electronics platform that consists of both hardware and software components. It was created to make it easier for hobbyists, students, and professionals to create interactive and programmable electronic projects. Arduino boards are microcontroller-based, which means they are small, single-board computers with built-in input and output pins that can be easily programmed to perform a wide range of tasks. Key features of Arduino include: Microcontroller: Arduino boards are typically built around microcontrollers from Atmel (now Microchip Technology) or other manufacturers. These microcontrollers provide the processing power for running Arduino programs (known as sketches). Development Environment: Arduino uses a user-friendly integrated development environment (IDE) that simplifies the process of writing, compiling, and uploading code to the A...
