3. Información de seguridade
Aviso: This kit involves soldering, which uses high temperatures and can produce fumes. Always follow these safety guidelines:
- Traballa nunha zona ben ventilada para evitar a inhalación de fumes de soldadura.
- Wear safety glasses to protect your eyes from splashes or flying debris.
- Usa un soporte para soldadores para evitar queimaduras accidentais.
- Asegúrate de que o soldador estea desconectado e arrefriado cando non o uses.
- Keep flammable materials away from your work area.
- Lávese ben as mans despois de manipular a soldadura.
- Keep out of reach of children unless under direct adult supervision.
4. Configuración e montaxe
This section guides you through the assembly process. A soldering iron, solder, and basic tools like wire cutters and needle-nose pliers are required (not included in this kit).
4.1. Preparación
- Unpack all components and verify against the "What's in the Box" list.
- Prepare your soldering workstation with adequate ventilation and lighting.
- Familiarize yourself with the PCB layout and component placement.
4.2. Soldering Components
Solder components in order from smallest to largest to ensure easier access. Start with resistors, then capacitors, crystal, and finally the IC socket and LEDs.
- Resistencias: Identify the resistors by their color codes or markings. Insert them into their designated positions (R1-R32) on the PCB. Bend the leads on the underside to hold them in place, then solder and trim excess leads.
- Capacitors and Crystal: Solder the small ceramic capacitors and the crystal oscillator into their respective positions. Ensure the crystal is securely seated.
- Microcontroller Socket: Place the DIP40 IC socket onto the PCB, aligning the notch on the socket with the notch on the PCB silkscreen. Solder all pins. This socket allows for easy insertion/removal of the microcontroller.
- LED: Carefully insert each of the 32 RGB LEDs into their designated holes. LEDs are polarized; ensure the longer lead (anode) goes into the hole marked with a '+' or the square pad, and the shorter lead (cathode) goes into the round pad. Solder each LED and trim the leads.
- Interruptor de alimentación: Solder the power switch into its position.
- Battery Holder Wires: Connect the red wire from the battery holder to the '+' pad and the black wire to the '-' pad on the PCB.

4.3. Microcontroller Installation
Gently insert the STC89C58RD microcontroller into the soldered IC socket. Ensure the notch on the microcontroller aligns with the notch on the socket and PCB. Apply even pressure to avoid bending pins.
4.4. Acrylic Case Assembly
- Remove the protective film from all acrylic pieces.
- Attach the stand piece to the bottom of one heart-shaped acrylic cover using the provided screws.
- Carefully place the assembled PCB into the acrylic cover with the stand.
- Align the second acrylic cover on top and secure it with the remaining screws. Ensure the power switch is accessible.

5. Instrucións de funcionamento
Once assembled and batteries are installed, operating the Heart Shaped LED Light is straightforward.
- Encendido: Locate the power switch on the side or bottom of the acrylic case. Slide the switch to the "ON" position.
- Pantalla de luz: The 32 RGB LEDs will immediately begin to display a variety of colorful patterns and effects. The microcontroller is pre-programmed with multiple light show sequences.
- Apagado: Para apagar o dispositivo, deslice o interruptor de alimentación á posición "OFF".

6. Mantemento
- Limpeza: Use a soft, dry cloth to gently wipe the acrylic case. Avoid abrasive cleaners or solvents.
- Substitución da batería: If the LED light show becomes dim or stops working, replace the two AAA batteries. Ensure correct polarity.
- Almacenamento: Store the kit in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, remove the batteries to prevent leakage.
- Inspección de compoñentes: Periodically check soldered joints for any signs of corrosion or loose connections. Re-solder if necessary.
