Arduino vs Raspberry Pi: The Ultimate Comparison

This is one of the most common questions among beginners. The answer isn't "one is better"—it depends on your project.

The Fundamental Difference

• Arduino: A Microcontroller. Runs a single program (your "sketch") in a loop. No operating system. Great for real-time sensor reading and motor control.
• Raspberry Pi: A Single-Board Computer (SBC). Runs a full operating system (Linux). Can multitask, browse the web, run Python scripts, and even play videos.

Head-to-Head

| Feature | Arduino Uno | Raspberry Pi 5 | | :--- | :--- | :--- | | Type | Microcontroller | Single-Board Computer | | Processor | 16 MHz AVR (8-bit) | 2.4 GHz ARM Cortex (64-bit) | | RAM | 2 KB | 4 GB / 8 GB | | Storage | None (Flash for code) | MicroSD Card | | OS | None | Linux (Raspberry Pi OS) | | GPIO | Yes (5V tolerant) | Yes (3.3V logic!) | | USB, HDMI, WiFi | No | Yes | | Price (India) | ~₹500 | ~₹5000 |

When to Use Arduino

• Reading sensors and controlling motors directly.
• Projects that need to run 24/7 on low power (e.g., irrigation).
• Beginners learning C++ and electronics.

When to Use Raspberry Pi

• Projects needing image/video processing (e.g., face recognition).
• Running a web server or database.
• AI/ML at the edge.
• When you need to run Python scripts.

Can You Combine Them?

Absolutely! Use an Arduino for real-time sensor work and a Raspberry Pi as the "brain" that handles networking, AI, and user interface. They can communicate via Serial (USB).
