How Arduino Works

Arduino is an open-source microcontroller platform. It runs one program in a loop—no operating system—making it ideal for real-time sensor and motor control.

Core Concepts

• setup() – Runs once at startup
• loop() – Repeats continuously
• GPIO Pins – Digital (0/1) and analog input
• PWM – Pulse Width Modulation for motor speed, LED dimming

Programming Flow

1. Initialize pins in setup()
2. Read sensors (analogRead, digitalRead)
3. Process data
4. Control outputs (digitalWrite, servo, motor)

Why Students Choose Arduino

• Easy C-style syntax
• Huge library support
• Affordable hardware
• Perfect for embedded systems basics
