If you’ve heard of Arduino, you’ve likely heard of Raspberry Pi too. It’s another favorite board among makers worldwide. But did you know? “It’s not just a microcontroller.” It is a full-fledged computer that’s extremely popular in the IoT world. Today, let’s get to know it better.
What is Raspberry Pi?
Raspberry Pi is a Single Board Computer (SBC) about the size of a credit card, developed by the Raspberry Pi Foundation in the UK.
What makes it cool is that it has everything a big computer has! CPU, RAM, GPU, USB ports, Ethernet, Wi-Fi, Bluetooth, and importantly, an HDMI port for connecting to a monitor. It runs Linux operating systems (like Raspberry Pi OS) just like a regular computer.
Amazing Specs (Example: Raspberry Pi 5)
- CPU: Quad-core Arm Cortex-A76 (Desktop-level performance)
- RAM: Available from 4GB to 8GB
- Video: Supports dual 4k displays!
- Connectivity: Gigabit Ethernet, Wi-Fi 5, Bluetooth 5.0
What Can You Do with Raspberry Pi?
Since it’s a computer, it can do almost anything a PC can, but with much lower power consumption and a compact size. It performs well in various projects, such as:
- Home Automation Hub: Control smart home devices via Home Assistant.
- Media Center: Turn a regular TV into a Smart TV for movies and music.
- Retro Gaming Console: Play classic games from the past.
- Desktop PC: Use for documents, web browsing, or learning Python/Scratch programming.
- AI & Image Processing: Connect a camera for face detection or object recognition using OpenCV.
Raspberry Pi vs. Arduino: What’s the Difference?
| Feature | Arduino | Raspberry Pi |
|---|---|---|
| Type | Microcontroller | Computer (SBC) |
| OS | None (Runs single loop code) | Yes (Linux, Windows IoT) |
| Power | Low (Good for hardware control) | High (Good for processing) |
| Energy | Very Low (batteries last long) | Higher (needs power adapter) |
| Strengths | Real-time, Robust, Simple | Multitasking, Connectivity, Display |
Simple Summary: If you need to “toggle lights/read sensors”, go with Arduino. If you need to “process images/run a server/display on a screen”, you need Raspberry Pi.
Getting Started Essentials
- Raspberry Pi Board
- Micro SD Card (for the OS)
- Power Adapter (Recommend 5V 3A or higher)
- HDMI Cable and Monitor
- Mouse and Keyboard
That’s it! You’re ready to step into the world of Linux and advanced IoT!
