Crash Course: 4주 만에 배우는 Arduino 기본

 🛠️ Key Concepts:
Introduction to Arduino: What is it? How does it work?
Setting Up the Arduino IDE (Software for coding)
Digital Outputs: Turning an LED ON and OFF
Basic Coding: pinMode(), digitalWrite(), delay()

🎯 Mini Project: Morse Code Blinker
Goal: Program an LED to blink in Morse Code.
Skills Gained: Writing a basic program, understanding delays and loops.
Challenge: Modify the code to blink your initials in Morse Code. 

 🛠️ Key Concepts:
Analog Inputs: How sensors work (photoresistor)
Reading Sensor Data: analogRead()
Conditional Statements: if statements to control LEDs
Serial Monitor: Displaying sensor data for debugging

🎯 Mini Project: Automatic Night Light
Goal: Build a light-sensing LED that turns ON in the dark.
Skills Gained: Reading sensor values, setting a threshold for control.
Challenge: Adjust the brightness of the LED based on the light level. 

 🛠️ Key Concepts:
Digital Inputs: Reading button presses
Random Delays: random() function
Timing Events: millis() function for measuring reaction time
Game Logic: Creating a simple game structure

🎯 Mini Project: Reaction Speed Game
Goal: Press a button as fast as possible when an LED turns on.
Skills Gained: Using timing functions, creating user interactions.
Challenge: Store the fastest reaction time in memory and display it. 

 🛠️ Key Concepts:
Sound Generation: tone() function to play musical notes
Multiple Inputs: Using multiple buttons
Frequency & Pitch: Understanding how sound waves work

🎯 Mini Project: Mini Piano
Goal: Use buttons to play different musical notes on a buzzer.
Skills Gained: Generating tones, handling multiple inputs.
Challenge: Add more notes or program a pre-set melody.
