Summary of "What's the difference? Arduino vs Raspberry Pi"

Core distinction

Arduino is a microcontroller board: a self-contained chip that stores, runs, and executes uploaded programs on the device. It is low-power, simple, and designed to control electronics directly.
Raspberry Pi is a single-board computer built around a microprocessor. It includes separate RAM, GPU, USB, network/audio interfaces, runs Linux, and behaves like a full computer.

Best suited for direct control of motors, lights, sensors and other hardware in robotics and embedded projects.
Uses a microcontroller that, once programmed from a PC, can run standalone (often battery-powered).
Programming: typically uses the Arduino IDE with a C/C++-like language. Third-party options exist for Python or block-based tools.
Hardware expandability: shields (stackable add-on boards) provide Bluetooth, cellular, Ethernet, motor control, LCDs, etc.
Available in many form factors and sizes for different project needs.
Low complexity and low power consumption — recommended for beginners and simple sensor/robotics tasks.

A full single-board computer (microprocessor + supporting chips). Runs Linux and can be used like a desktop.
Built-in peripherals vary by model but commonly include USB, HDMI/graphics, audio, Wi‑Fi, Bluetooth, and Ethernet.
Higher power requirements and greater software/hardware complexity than an Arduino.
Has GPIO (general-purpose input/output) pins for controlling hardware such as lights, motors, sensors, and LCDs.
Programming: Python is the primary language for GPIO work; many other languages and libraries are available.
Expandability: HATs (Hardware Attached on Top) add pre-made functionality via the GPIO header.
Available in multiple sizes/models to suit different project requirements.

Choose Arduino when your goal is straightforward hardware control, low power consumption, or an embedded standalone device (e.g., simple robot, sensor node).
Choose Raspberry Pi when you need general-purpose computing capabilities: running a web server, USB storage, webcam streaming, or other OS-level/networking tasks.
Examples:
- Bluetooth-controlled toy car (no livestreaming): Arduino is ideal.
- Bluetooth-controlled car that livestreams to Twitch: Raspberry Pi is better.
Beginner recommendation: start with Arduino to learn hardware fundamentals, then move to Raspberry Pi for more complex, OS-level projects.

Arduino workflow: connect to a PC to upload code, then the board can run independently.
Raspberry Pi workflow: it is a computer, so you can program directly on the device.
Both ecosystems offer rich libraries, community tutorials, and add-on hardware (shields for Arduino, HATs for Raspberry Pi).
Typical learning path: learn Arduino for hardware basics, then integrate a Raspberry Pi when you need cameras, web interfaces, or heavier I/O and processing.
