Automated Plant Watering System

This Java application reads moisture levels from a sensor and controls a water pump based on those readings. It also displays the moisture level on an OLED screen and plots the data over time using StdDraw.

Features

• Moisture Sensing: Continuously reads moisture levels from a connected sensor.
• Water Pump Control: Activates a water pump based on moisture levels.
• Data Visualization: Plots moisture levels over time using StdDraw.
• OLED Display: Shows real-time moisture levels and status messages on an OLED display.

Requirements

• Java: Ensure you have Java installed on your system.
• Libraries:
  • Firmata4j: For communication with the Arduino board.
  • StdDraw: For plotting the moisture levels.
  • JSSC: For serial communication (Windows users).
• Hardware:
  • Arduino board
  • Moisture sensor
  • Water pump
  • OLED display

2. Connect Hardware:

   • Connect the moisture sensor to the analog pin (Pin 14).
   • Connect the water pump to the digital output pin (Pin 2).
   • Connect the OLED display via I2C.

3. Configure the Port:

   • Update the myPort variable in the code with the correct port name for your Arduino board (e.g., COM3 for Windows or /dev/ttyUSB0 for Linux).
   • Update the Hardware pins or addresses for your Arduino Circuit/Board.

Troubleshooting

• Connection Issues: Ensure the correct port is specified and that all hardware is properly connected.
• Library Issues: Verify that all required libraries are included in the classpath.
