Enhance Smart Irrigation System Code for Readability, Safety, and Features #1
Description
The current Arduino code for the smart irrigation system is functional but can be improved for readability, maintainability, and robustness. Let's track the enhancements in the following areas:
Proposed Enhancements
1. Code Organization & Readability
- Refactor code into smaller functions and group related logic.
- Add more comments and improve variable naming where needed.
- Move constants and configuration to a dedicated section.
2. Safety & Reliability
- Add debounce logic for button presses to prevent accidental multiple triggers.
- Implement error handling for OLED initialization and sensor failures.
- Ensure relay and pump always revert to safe state on setup or error.
3. Features & Usability
- Add persistent configuration for pump duration (EEPROM).
- Provide clearer feedback on OLED (e.g., pump countdown always visible, error/status messages).
- Optional: add calibration mode for moisture thresholds.
- Optional: add a mode to test buzzer and relay functions.
- Optional: enable/disable buzzer via button or menu.
4. Documentation
- Add code comments explaining major logic blocks.
- Provide a wiring diagram and usage instructions in the repository README.
Acceptance Criteria
- Code is modular, safe, and well-documented.
- Basic and advanced users can understand and modify the code.
- System fails safe in case of errors.
Feel free to split this into multiple PRs or issues for granularity. Suggestions and further feature ideas are welcome!
