2. Linji Gwida dwar is-Sigurtà
Soldering involves high temperatures and can produce fumes. Always adhere to the following safety precautions:
- Aħdem f'żona ventilata sew biex tevita li tieħu n-nifs tad-dħaħen tal-istann.
- Wear appropriate eye protection (safety glasses) to protect against splashes or flying debris.
- Uża stand tal-ħadid tal-issaldjar biex tevita ħruq aċċidentali.
- Ensure the soldering iron is unplugged and cooled down when not in use.
- Handle electronic components carefully to avoid damage from static electricity.
- Żomm apparat tat-tifi tan-nar jew kutri tan-nar fil-qrib.

4. Istruzzjonijiet tal-Immuntar (Setup)
Follow these steps carefully to assemble your humidifier kit. Refer to the 'Step By Step Instruction' section within Image 2 for visual guidance on component placement and soldering.
- Prepare the PCB: Identify all component locations on the PCB.
- Solder Surface Mount Components (SOT-23 MOSFET): This is the smallest component. It is recommended to solder one pad first, align the component with tweezers, then solder the remaining pads. The kit includes extra MOSFETs in case of error.
- Reżisturi tal-Istann: Match resistor values to their designated spots on the PCB. Resistors are not polarized.
- Solder Diodes: Pay attention to the polarity (band on the diode matches the marking on the PCB).
- Kondensaturi tal-Istann: Electrolytic capacitors (larger, cylindrical) are polarized; ensure the longer lead (positive) matches the '+' marking on the PCB. Ceramic capacitors (smaller, disc-shaped) are not polarized.
- Solder LED: The longer lead of the LED is positive and should match the '+' marking on the PCB.
- Solder 2-pin Sockets: Solder the small 2-pin headers into their designated spots.
- Solder Temperature & Humidity Sensor (DHT11): Bend the pins as needed and solder the sensor into place.
- Solder Push Buttons: Solder the four small push buttons and the larger power button into their respective positions.
- Solder Micro USB Port: Carefully solder the Micro USB port to the PCB.
- Assemble Humidifier Module: Insert the piezoelectric element into its black plastic housing. The larger of the two openings on the housing should face upwards. Route the piezo wires through the square hole where the two halves meet.
- Mount OLED Display: Solder the OLED display module to its designated header pins on the PCB.
- Assemble Enclosure: Use the provided screws and standoffs to secure the PCB between the acrylic plates. Ensure the humidifier module is correctly positioned with the cotton stick extending downwards.
