3.2. Electrical Connections
Carefully connect the electronic components as follows:
- Connect the SG90 Servos to the Expanding Board using the 3pin F-F Dupont cables. Refer to the Arduino code for specific pin assignments.
- Connect the Photoresistive Sensors to the analog input pins on the Expanding Board.
- Connect the Solar Panel output to the appropriate input on the 18650 Mobile Power Shield.
- Connect the 18650 Battery Case to the 18650 Mobile Power Shield.
- Connect the Charge Detector inline with the USB charging output if desired.
- Ensure all connections are firm and correct to prevent damage to components.

4. Operating Instructions
4.1. Automatic Solar Tracking
Once assembled and powered on, the kit's photoresistive sensors will detect the direction of the strongest light source (e.g., the sun). The Arduino board will then control the SG90 servo motors to adjust the solar panel's angle, ensuring it is always facing the light for maximum energy absorption. The system is designed for multi-angle rotation, typically up to 180 degrees horizontally and vertically.

4.2. USB Charging Output
The 18650 Mobile Power Shield provides a USB output port. After the internal 18650 batteries (not included) have been charged by the solar panel, you can connect your mobile phone or other USB-powered devices to this port to charge them. The Charge Detector can be used to monitor the charging voltage and current.

4.3. USB Power Adapter Charging Input
The 18650 Mobile Power Shield also features a Micro USB input. You can charge the internal 18650 batteries using a standard USB power adapter (e.g., a phone charger) and the provided Micro USB cable. This allows you to charge the batteries even when solar power is not available.

5. Maintenance
- Cleaning: Keep the solar panel surface clean from dust and debris to ensure optimal light absorption. Use a soft, damp cloth for cleaning.
- Connections: Periodically check all electrical connections to ensure they are secure and free from corrosion.
- Environment: Store and operate the kit in a dry environment, away from direct moisture or extreme temperatures, to prolong its lifespan.
- Batteries: If using 18650 batteries, ensure they are in good condition and charged regularly. Replace them if they show signs of degradation.
6. Troubleshooting
- Kit not powering on:
- Check if the 18650 batteries are correctly inserted with the right polarity.
- Ensure the power switch (if present) is in the ON position.
- Verify all power connections to the Arduino board and Mobile Power Shield.
- Solar panel not tracking light:
- Ensure the photoresistive sensors are correctly wired and exposed to light.
- Check the connections of the SG90 servo motors to the Expanding Board.
- Verify that the Arduino code for tracking is correctly uploaded and running.
- Ensure there is sufficient light for the sensors to detect a difference.
- Mobile phone not charging via USB output:
- Check if the internal 18650 batteries are sufficiently charged.
- Verify the USB cable connection between the kit and your phone.
- Ensure the Charge Detector (if used) is functioning correctly.
- Kit not charging via USB power adapter:
- Ensure the Micro USB cable is securely connected to the Mobile Power Shield and the power adapter.
