In short, we can say that Arduino is the brain of thousands of projects. In short, we can make devices that react and respond to the world by using this board. It can also interact with motors, sensors, and electromagnets. It can interact with anything that is controlled by electricity in any way. It is based on ATMEL ATmega328p microcontroller. There are many other microcontrollers like PIC microcontrollers, ST microcontrollers, Texas microcontrollers but Arduino is used mostly as it is inexpensive and can be used in various forms. Arduino Uno is known as an open-source development board as it allows you to use this board to interact with real-world things by uploading programs on this board.
