4. Assembly Instructions

Follow these steps carefully to assemble your LED Music Spectrum Display. It is recommended to have basic soldering skills and tools (soldering iron, solder, desoldering wick/pump, wire cutters, multimeter) before starting.

1. Component Identification: Sort all components and identify them using the provided component list and circuit diagram (if included). Pay attention to resistor color codes and capacitor polarity.
2. Resistor Installation: Solder all resistors onto the PCB. Start with the lowest height components first. Bend the leads, insert into the correct holes, and solder from the underside. Trim excess leads.
3. Diode Installation: Solder diodes, ensuring correct polarity (match the band on the diode to the marking on the PCB).
4. Capacitor Installation: Solder ceramic capacitors (non-polarized) and then electrolytic capacitors. For electrolytic capacitors, ensure the longer lead (positive) matches the '+' marking on the PCB, and the shorter lead (negative) matches the '-' or shaded area.
5. IC Socket Installation: Solder the IC sockets onto the PCB. Ensure the notch on the socket aligns with the notch marking on the PCB. Do not insert the ICs yet.
6. LED Installation: Solder the LEDs. LEDs are polarized; the longer lead is positive (+), and the shorter lead is negative (-). Match these to the PCB markings.
7. Other Components: Install any remaining components such as the microphone module, power jack, and switches.
8. IC Insertion: Carefully insert the Integrated Circuits into their respective sockets. Ensure the notch on the IC aligns with the notch on the socket and PCB. Bend the pins slightly inward if necessary to fit.
9. Casing Assembly: Assemble the acrylic casing around the completed circuit board using the provided screws and standoffs. Ensure all parts fit snugly and are secured.

5. Setup

Once assembly is complete, follow these steps to set up your LED Music Spectrum Display:

1. Power Connection: Connect the provided USB power cable to the display's power input port and then to a 5V USB power adapter (not included) or a computer USB port.
2. Audio Input: The display typically uses a built-in microphone to detect ambient sound. Ensure the microphone is not obstructed.
3. Placement: Place the display in a location where it can easily pick up audio from your music source.

6. Operating Instructions

Once powered on, the display will automatically begin to react to sound. Here’s how to use it:

• Power On: Connect the USB power. The LEDs should light up, indicating the device is active.
• Sound Detection: Play music or generate sound near the display. The LED columns will illuminate and fluctuate in height, representing different frequency bands of the audio spectrum.
• Adjusting Sensitivity (if applicable): Some kits may include a potentiometer to adjust the microphone sensitivity. If present, gently turn the knob to fine-tune how the display reacts to sound levels.
• Power Off: Disconnect the USB power cable to turn off the display.

7. Maintenance

• Cleaning: Use a soft, dry cloth to clean the acrylic casing. Avoid abrasive cleaners or solvents that could damage the plastic.
• Dust Removal: Periodically use compressed air to remove dust from the circuit board and microphone area to ensure optimal performance.
• Component Check: If the display malfunctions, visually inspect soldered joints for cold solder joints or bridges. Re-solder as necessary.
