Arduino is a widely used open source platform for the development of electronic and programming projects. It consists of a combination of hardware and software that allows users to create and control interactive devices in an easy and accessible way, without the need for advanced knowledge of electronics or programming. The main Arduino hardware consists of an electronic board with a microcontroller, which is the brain of the system. The Arduino board includes digital and analog inputs and outputs, as well as different connection pins that allow you to interact with other electronic components, such as sensors, actuators, lights, and displays. Range of hardware electronic devices and free software (Open Source) with a re-programmable microcontroller, ideal for developing electronic projects both at a professional level, as well as for education or home users.
