How It Works
The Arduino Uno R3 uses the ATmega328P microcontroller to execute uploaded programs (called sketches). Code is written in the Arduino IDE and transferred to the board via the USB connection.
Once programmed, the board can read input signals from sensors, buttons, and communication modules, process the data, and control outputs such as LEDs, displays, relays, motors, buzzers, and other electronic devices.
Its built-in communication interfaces (UART, SPI, and I²C) allow easy integration with hundreds of compatible modules, making it an excellent platform for learning electronics and developing embedded systems.
