Automatic Plant Watering with Arduino

This video tutorial demonstrates an automatic plant watering system using an Arduino. It covers the components involved, such as the Arduino Uno, LEDs, a soil moisture sensor, and a DC pump. The tutorial explains the circuit setup and provides a detailed walkthrough of the code, including how to customize and optimize the system for different plants and environments. It also discusses the importance of calibrating the sensor and managing the pump's operation to prevent overwatering.

What precautions should be taken to prevent the soil moisture sensor from oxidizing?

Describe how you would modify the system to water multiple plants.

What considerations should be made for the physical setup of the watering system?
