Arduino

An Arduino is an open-source microcontroller platform consisting of a programmable circuit board and development environment used for creating interactive electronic projects. It features digital and analog input/output pins that can interface with sensors, motors, LEDs, and other components, making it ideal for prototyping and learning electronics. Arduino boards are programmed using a simplified version of C++ through the Arduino IDE, allowing users to write code that controls hardware interactions. It's widely popular among hobbyists, students, and professionals for building everything from simple LED circuits to complex robotics and IoT projects.
