Learn CIRCUITPYTHON with Real Code Examples

Limited by microcontroller CPU and RAM

Real-time performance is sufficient for basic tasks

Heavy computation should be offloaded to host or optimized C modules

Efficient for rapid prototyping and low-power applications

Memory management is critical on small boards

Local device execution; limited network security features

Secure USB connection recommended for shared environments

Sensitive data should be carefully stored or transmitted

Firmware updates must come from trusted sources

Physical device access is primary security boundary

Use REPL for real-time debugging

Print statements for sensor and actuator monitoring

Log data to onboard files if needed

Test peripheral response under different conditions

Analyze output for optimization and correctness

Comment hardware control code clearly

Use functions to structure repeated actions

Validate sensor readings before acting

Test loops and event handling thoroughly

Keep code.py readable for beginners
