🔧 Hardware Connections Guide

LED Blink

Circuit: Connect LED to pin 13 (built-in LED)
Test: LED should blink when you send '1' (ON) or '2' (OFF)

Button Input

Circuit: Button to pin 2, LED to pin 13
Test: Press button → LED blinks, counter increments

PWM (Analog Write)

Circuit: LED with resistor to pin 11
Test: Send '3' → LED fades in/out
Send value: Send '4' then type number (0-255)

Analog Read

Circuit: Potentiometer to analog pin A0
Test: Read values in real-time

Traffic Light Project

Pins: Red (10), Yellow (9), Green (8)
Sequence: Green (3s) → Yellow (3s) → Red (5s) → Yellow (2s) → Repeat

🎮 How to Use the System

Serial Commands (via Desktop App or Serial Monitor)
