  • Echo Pin: Connect to digital pin 5.

🌿 I2C Sensor

  • SDA: Connect to Arduino's SDA pin.
  • SCL: Connect to Arduino's SCL pin.

⚙️ Stepper Motor

  • Direction Pin: Connect to digital pin 3.
  • Step Pin: Connect to digital pin 4.

🛠️ Setup Instructions

  1. Assemble the Circuit: Carefully connect all components as per the pin connections above using jumper wires. 🔌

  2. Configure CAN Module: Set up the MCP2515 CAN module with the CS pin connected to digital pin 10. Ensure the module is properly configured for communication with the Arduino.

  3. Connect Relays: Attach the solenoid valve, water pump, and grow light to their respective relays. Ensure the relays are capable of handling the current and voltage requirements of these components. 💡

  4. Set Up the Ultrasonic Sensor: Connect the Trig and Echo pins of the HC-SR04 ultrasonic sensor to digital pins 6 and 5, respectively. 📡

  5. I2C Sensor Configuration: Connect the I2C sensor for soil moisture and air parameters to the Arduino's I2C pins (SDA and SCL). Ensure that the sensor's address (0x40) does not conflict with other I2C devices. 🌿

  6. Install the Stepper Motor: Connect the stepper motor to the driver, ensuring that the direction pin is connected to digital pin 3 and the step pin to digital pin 4. 🚗

  7. Upload the Code: After making all connections, upload the provided Arduino sketch to your board. 💻

  8. Testing: Power up the Arduino and test each component to ensure they are functioning as expected. ⚡

⚠️ Safety Precautions

  • Double-check all connections before powering up the Arduino.
  • Ensure power ratings for relays and motors are within the specifications for your components.
  • Avoid making or altering connections while the power is on.
