An Arduino is an open-source electronics device based on easy-to-use hardware and software (embedded system). It designed for making an interactive project. The Arduino board can read inputs (from sensors) and turn into output (delivered IoT solutions). Use Arduino Software (IDE) for uploading code in Arduino board and work online. On the other hand, a microprocessor is an integrated circuit that contains the functions of a central processing unit (CPU) of a computer and also known as brain of computer. It performs arithmetic and logic operations, controls the timing of operations, and manages data flow in a computer system.
