One is a microcontroller, the other is a full computer. Learn when to use each for your electronics projects.
The Raspberry Pi is a full single-board computer (SBC) running Linux. It can browse the web, run Python, and handle AI/ML tasks.
The Arduino Uno is a microcontroller board. It runs a single program in a loop, making it perfect for real-time sensor and actuator control.

Choose **Arduino** for real-time sensor control, robotics, and low-power embedded systems. Choose **Raspberry Pi** for AI, image processing, web servers, or when you need a full OS.
They serve different purposes! Use Arduino for hardware control and Raspberry Pi for software-heavy tasks. Many advanced projects use BOTH together.
