My dad wanted me to make it so I did it.

EXPANDED TECHNICAL DETAILS

Precision Fluid Control Logic

This project provides a robust solution for automating water flow in gardens, aquariums, or industrial setups.

  • High-Current DC Switching: Manages a 12V Solenoid Valve using a high-performance IRFZ44N MOSFET or a Relay. The Arduino isolates its logic from the valve's inductive kickback using an 1N4007 flyback diode.
  • Timer-Based Automation: Features a custom-programmable "Schedule" where the valve opens for a specific duration (e.g., 10 minutes) every 24 hours.

Safety and Verification

  • Moisture-Linked Override: (Advanced version) Integrates a soil moisture sensor; the solenoid will only open if the soil is below the dryness threshold, saving water and protecting plants.
