Arduino is an open-source computer hardware/software platform, software company, and user community designed to build single-board microcontrollers. These are small computers on single-circuit boards, which provide all the circuitry necessary for products such as TVs, refrigerators, radios, washing machines, dishwashers, and other household items.
Arduino is important to learn in order to easily and inexpensively build devices. It can be utilized for personal or professional use. Arduino is beneficial for hobbyists and businesses alike because it has the potential to create better products thanks to low-cost prototyping and iterating.
