  • Sensor-based applications

Key Differences and Application Areas:

• Arduino: Best for simpler, low-power, and embedded projects, especially those involving basic microcontroller tasks like controlling sensors, actuators, or motors. It is ideal for beginners, educational projects, and small-scale automation systems.
• Raspberry Pi: Suited for more complex tasks such as running full operating systems, advanced computing tasks, and multimedia processing. Raspberry Pi excels in IoT, personal computing, media centers, and robotics that require more computational power.

Conclusion:

If your project demands higher processing power, a full OS, or multimedia capabilities (e.g., media servers, advanced IoT), Raspberry Pi is a better fit.

If your project requires real-time control, low power, and is relatively simple (e.g., robotics, home automation), Arduino is a better choice.
