How to Use the Arduino Uno Rev3 Board

1. Connect the board to a computer using a standard USB cable.
2. Install the Arduino IDE (or the environment specified by your course).
3. Select the correct board and port settings in the software.
4. Write or open a program (sketch) for your exercise.
5. Upload the program to the board and observe its behaviour.
6. Connect additional sensors, LEDs, or modules to the digital/analog pins as needed.
7. Modify and re-upload the program to build understanding through iteration.

Specifications

Compatibility & Safety Note

• Use a regulated power source within the board’s rated input voltage range.
