Arduino Fundamentals: From Basics to Cool Projects

Identify Arduino board anatomy: microcontroller, GPIO pins, power jack, USB interface, reset button, onboard LEDs

Install and navigate the Arduino IDE: verify/upload buttons, serial monitor, library manager, board/port selection

Apply basic electronics safety: current limits per pin (40 mA), total board current, short-circuit prevention, proper wiring practices

Read and build simple breadboard circuits: power rails, terminal rows, jumper wires, component placement

Understand the edit-compile-upload-run cycle and interpret common compilation error messages

Execute the 'Blink' sketch: modify delay values, change LED pin, explain setup() vs loop() execution flow
