Arduino is an open-source electronics platform based on easy-to-use hardware and software. It consists of microcontroller boards that can read inputs (like sensors, buttons, or light detectors) and control outputs (such as LEDs, motors, or displays). Key Features: * Microcontroller-Based: Uses ATmega or ARM microcontrollers. * Open-Source: Hardware and software are freely available. * User-Friendly Programming: Uses the Arduino IDE with a simplified version of C/C++. * Large Community: Tons of tutorials, projects, and support online. Common Arduino Boards: * Arduino Uno – The most popular board, ideal for beginners. * Arduino Mega – More memory and pins for bigger projects. * Arduino Nano – Compact and great for embedded applications. Arduino Leonardo – Can act as a USB keyboard or mouse. What Can You Do with Arduino? * Build robots * Automate home appliances * Create IoT projects * Design wearable tech * Make musical instruments * And much more!
