📚 Background Theory

🔬 Microcontroller Fundamentals

At the heart of every Arduino board lies a microcontroller — a compact integrated circuit designed to govern a specific operation in an embedded system.

A microcontroller typically contains:

• CPU (Central Processing Unit)

• RAM (Volatile Memory)

• Flash Memory (Program Storage)

• I/O Ports

• Timers and Counters

• Communication Interfaces (UART, SPI, I2C)

Unlike general-purpose computers, microcontrollers:

• Execute one main program continuously

• Operate in real-time

• Interact directly with hardware

⚡ Embedded Systems Architecture

An embedded system consists of:

1. Hardware Layer

2. Firmware Layer

3. Application Logic

Arduino simplifies this stack by offering:

• Pre-built hardware boards

• Bootloader firmware

• Simplified C++-based programming environment

🔄 Digital vs Analog Systems

Arduino interacts with both digital and analog signals.

Digital Signals

• Binary: 0 (LOW) or 1 (HIGH)

• Used for buttons, relays, LEDs

Analog Signals

• Continuous voltage values

• Read via ADC (Analog-to-Digital Converter)

🧠 Control Systems Basics

Arduino projects often involve:

• Feedback systems

• Sensors and actuators

• PWM (Pulse Width Modulation)

• PID controllers

These principles are used in robotics, automotive systems, HVAC systems, and industrial automation.
