Study Notes
Arduino Uno Components
- The USB connector is used to connect the Arduino Uno to a computer, enabling programming and communication between the two devices.
- The power jack (Barrel connector) is used to power the Arduino Uno from an external power source, such as a wall adapter or battery, allowing it to operate independently.
Microcontroller
- The ATmega328P is the microcontroller on the Arduino Uno, responsible for executing the program instructions and controlling the board's operations.
Digital Pins
- The Digital Pins on the Arduino Uno are used for digital input/output operations, such as reading switches, controlling LEDs, and communicating with other digital devices.
Analog Pins
- The Analog Pins on the Arduino Uno are used for analog input operations, such as reading sensors, potentiometers, and other analog devices, allowing the board to interpret analog signals.
