• 14 ANIMATION MODES AND 7 SPECTRUM MODES: PEMENOL DIY LED tower kit has 14 animation modes and 7 spectrum modes.You can use the audio extender in the kit to connect the LED Tower kit to a computer, phone or speaker for spectrum functions. When music is played, the lights dance to the rhythm of the music.
• PERFECT DECORATION: PEMENOL LED kit is the perfect gift for friends, family, or even for yourself. Whether placed on your desk, living room, or bedside, it will serve as a perfect decoration, providing you with some joy when you're feeling tired. Additionally, the extended soldering time can help improve a child's focus and soldering skills.
• MANUAL IN PAPER: PEMENOL LED electronic kit components include manual in paper, components are packed separately in transparent bags. So that you can understand the product more easily and start soldering. Detailed PDF instructions can be downloaded from the Product guides and documents section of the Product page.

Detailed Install Instruction Download

Install 11pcs 510ohm Metal Film Resistor at R1-R11.

Install 1pcs 10Kohm Metal Film Resistor at R13.

Install 1pcs DIP-28 IC Socket at U1.

Look for the gap mark on one end of the IC socket and match it with the gap mark on the PCB silk screen. This will show you the correct direction to install the IC socket.

Install a Mini USB Port at P3

Install 2pcs Toggle Switch at S1,S2.

Install one 220uF electrolytic capacitor at C1.

Make sure to distinguish between the positive and negative terminals. The longer pin is the positive terminal.

NOTE: The capacitor must be placed horizontally, otherwise, you won't be able to install the following components.

1. According to the length of the LED lead to distinguish. The longer pin is positive(anode) lead. The shorter pin is negative(cathode) lead.

2. Identify the negative(cathode) of the LED is to look into the plastic case where one can see that the negative(cathode) is much thicker/bigger inside the plastic case than the anode lead.

3. Identify by edge of plastic case.The negative(cathode) lead of the LED should be the pin nearest the flat on the plastic case.

4. Test by 3V battery or multimeter.The pin is positive(anode) lead which has connect to the positive of 3V if LED can light up after connect 3V power supply.(LED should not be powered directly from the 3V for a short time:less then 0.5second)

5. It is positive(anode) where the white mark “+” pointing to on PCB.

Install four 5mm RGB LEDs at D1 to D4.

The LONGER pin is the POSITIVE terminal and should be connected to the SQUARE PAD.

Install one Infrared Receiver at P4.

Install one DIP-28 IC STC15W408AS Amplifier or IC Socket at U1.

There is a GAP mark on one end of the IC and also on the PCB silk screen where the IC is to be placed. These two marks correspond to each other and indicate the correct direction for installing the IC.

Test the circuit by powering it on. The circuit is working correctly if the four LEDs flash automatically.

Install four M3*20mm Nylon Columns and four M3*6mm Nylon Screws on the LED Soldering Template.

Follow the rules shown in the diagram, where the outermost ring is the first ring (1st Ring) and the innermost ring is the sixth ring (6th Ring).

The 1st to 9th rings are labeled for reference.

The diagram shows the structure of each layer of LEDs. The first layer of LEDs is the closest to the PCB.

Prepare the LEDs by bending the longer pin (positive pole) at a right angle.

Be careful not to damage the LED while doing so.

Assemble the first layer of the LED tower main body.

Place the prepared LED on the first ring (#1 Ring) with the shorter pin (negative pole) facing outward and the longer pin (positive pole) connecting to the next LED.

Use a soldering iron to solder the positive pole (longer pin) of the LED in place.

Be careful not to touch the LED pins with the soldering iron for too long, as it may damage the LED.

Cut off any excess pins, but only CUT the LONGER PINS!

Use the same method to make the 2nd to 9th layer of LED for the Tower main body. Follow the LED Soldering Template.

The spire has four layers of LEDs, distributed as 6-6-1-1.

This means that the 1st and 2nd layers have 6 LEDs each, while the 3rd and 4th layers have 1 LED each.

Take out the 4 M3*20mm Nylon Column and 4 M3*6mm Nylon Screw from the LED Soldering Template and put them on the PCB.

Bend the LED pins at a 45-degree angle.

Install the 1st layer of LEDs onto the PCB, ensuring that they are level.

Use a white wire to connect the positive pole of the 1st layer to T1.

After connecting and turning on the power, this layer should flash normally.

Make it easier to connect and secure the next layer.

Attach the second layer of LEDs to the PCB and connect it to T2.

Test the connection afterwards.

Tip: Secure the diagonal LEDs first, and then attach the rest of the LEDs.

Mount the third to ninth layers of LEDs on the PCB and connect them to T3 to T9 respectively.

Test the connection using the same method as before.

Note: The sixth layer is the smallest LED ring.

Bend the LED pins at an angle of 45 to 135 degrees and apply some solder to the ends.

Note: The LED pins are the negative pole on the outermost part.

Then connect two 6pcs-LED-Ring to the 9th ring by metal wire.

Note that they are connected by their internal metal rings.

NOTE: LED pins are negative pole at outermost.

Test after power ON.
