- Why Code Quality Matters
- Clean code is easier to understand, fix, and improve.
- Badly written code may work once but fail later due to hidden problems.
- How to Structure Code
- Use clear variable names (e.g., temperatureValue instead of temp1).
- Break your program into functions for different tasks (e.g., setupSensor(), readTemp()).
- Keep related code together and organized.
- Code Comments
- Comments are notes inside code (written after // in Arduino or # in Python) that explain what a section does.
- They help you and others understand the purpose of each part without guessing.
- Debugging Basics
- Debugging means finding and fixing mistakes in your code.
- Common debugging tools:
- Serial Monitor (Arduino)
- Print statements (Python)
- Step-by-step testing
- Optimization Basics
- Optimization means making your code run faster or use less memory.
- Examples: Removing unnecessary loops, avoiding repeated calculations, using efficient logic.
