3.2 Connecting Modules to the Controller Board

1. Attach the Sensor Shield to the KEYESTUDIO PLUS Controller Board.
2. Connect each sensor and actuator module (e.g., photocell, PIR, LEDs, servo, fan, LCD) to the appropriate pins on the Sensor Shield using the provided jumper wires. Ensure correct polarity and pin assignments as per the online tutorials.
3. Connect the Bluetooth module to its designated serial communication pins.

3.3 Softwareopsætning

1. Download og installer Arduino IDE fra den officielle Arduino webwebsted (www.arduino.cc/en/software).
2. Install the necessary drivers for the KEYESTUDIO PLUS Controller Board (CP2102 chipset). These drivers are typically available on the KEYESTUDIO website or through the Arduino IDE's board manager.
3. Add the KEYESTUDIO board definitions to your Arduino IDE.
4. Install any required libraries for the sensors and modules used in the kit. Instructions for library installation are provided in the online tutorials.

3.4 Powering the Kit

• Insert 6 AA batteries into the battery holder.
• Connect the battery holder to the power input jack on the KEYESTUDIO PLUS Controller Board.
• Alternatively, you can power the board via the USB-C cable connected to a computer.

4. Betjeningsvejledning

Once assembled and programmed, the smart home kit offers various interactive functions. The core functionality relies on uploading code to the Arduino board, which then controls the sensors and actuators.

4.1 Initial Program Upload

1. Connect the KEYESTUDIO PLUS Controller Board to your computer via the USB-C cable.
2. Åbn Arduino IDE og indlæs example code provided in the online tutorials for the smart home kit.
3. Select the correct board (KEYESTUDIO PLUS or Arduino Uno) and COM port from the "Tools" menu.
4. Click the "Upload" button to transfer the code to the board.

4.2 Smart Home Functions

• Light and People Photocell Sensor: Detects ambient light levels and human presence to control lighting.
• Human Infrared (PIR) Sensor: Detects motion, often used for security or automated lighting.
• LED Modules: Control the white and yellow LEDs for various indications or lighting effects.
• Soil Humidity Sensor: Monitors soil moisture levels, useful for plant care reminders.
• Gas Leak Alert: Detects the presence of certain gases, triggering an alert.
• Steam Sensor: Detects steam or high humidity levels.
• Bluetooth Remote App Control: Control various functions of the smart home using a dedicated mobile application (Android/iOS).
• Knapkontrol: Interact with the system using physical buttons, for example, to open doors with a specific sequence (Morse code).
• Fan Module: Activates a fan, potentially for ventilation or cooling.
• Servo motor: Controls the movement of elements like doors or windows.

5. Vedligeholdelse

5.1 Udskiftning af batteri

If the smart home model is powered by batteries, replace the 6 AA batteries when performance degrades or the system becomes unresponsive. Ensure correct polarity when inserting new batteries.

5.2 Rengøring

Gently wipe the wooden surfaces and electronic modules with a dry, soft cloth. Avoid using liquids or abrasive cleaners, as these can damage the electronic components or the wooden structure.

5.3 Softwareopdateringer

Periodically check the KEYESTUDIO official website or wiki for updated code examples, libraries, or software drivers to ensure optimal performance and access to new features.

6. Fejlfinding

Dette afsnit omhandler almindelige problemer, du kan støde på under montering eller betjening.

• Issue: Code upload fails.
  • Løsning: Ensure the correct board and COM port are selected in the Arduino IDE. Verify that the USB-C cable is securely connected and the necessary drivers (CP2102) are installed.
• Issue: Mobile app crashes or Bluetooth connection is unstable.
  • Løsning: Ensure the Bluetooth module is correctly wired and powered. Try restarting the app and the smart home kit. Check for app updates or alternative compatible Bluetooth control applications.
• Issue: A specific sensor or module is not responding.
  • Løsning: Verify all wiring connections for the module are correct and secure. Check the code to ensure the module is initialized and read/written to properly. Test with a simple example sketch for that specific module.
• Issue: Servo motor or fan module gets stuck or does not move.
  • Løsning: Ensure there are no physical obstructions. Check power supply; motors require sufficient current. Verify the code sends correct control signals and that the module is properly connected.
• Issue: LCD display shows no text or incorrect characters.
  • Løsning: Adjust the potentiometer on the back of the LCD module to control contrast. Ensure the correct LCD library and initialization code are used.
