Ease of use for beginners

Hardware abstraction via built-in libraries

Rapid prototyping and deployment

Cross-platform support

Open-source and community-driven development

Modularize sketches with functions

Use libraries for reusable code

Move computation-heavy tasks to external processors

Use interrupts instead of blocking delays

Combine multiple boards for distributed systems

Move from Arduino Uno to Mega/Nano for more I/O

Switch to ESP32 for Wi-Fi/Bluetooth
