43 LED Electronic Windmill DIY Soldering Kit – 9 Animated Light Patterns

Build your own mesmerizing LED light display with this hands-on DIY electronic soldering kit! Featuring 43 LEDs driven by a pre-programmed DX158 microcontroller, this kit produces nine stunning animated patterns once assembled — perfect for electronics enthusiasts, students, and hobbyists looking to sharpen their soldering and circuit-building skills.

⚠️ Important Notice: This kit is intended for buyers who already have experience with electronic circuits and soldering. We guarantee components are in good condition upon delivery, but successful assembly depends on the builder's skill level. Please read all instructions carefully before purchasing.

Note: The PCB (circuit board) may be black or green — color is assigned at random. If board color is important to you, please keep this in mind before ordering.

9 Animated LED Display Patterns

Power it on and scroll through nine eye-catching animations using the onboard S3 switch:

• 🌀 Forward Windmill
• 🌀 Reverse Windmill
• 🌸 Rotating Petal
• ⏳ Rotating Pendulum
• 🐏 Rotating Sheep Horn
• 🌺 Petal Blooming
• ❄️ Snowflake Formation
• ⭕ Concentric Diffusion
• 🔵 Rotating Ellipse

Use S1 to slow the animation speed and S2 to speed it up — giving you full control over the display effect.

Key Features

• 43 LEDs arranged in a row/column matrix for dynamic, flowing light effects
• Pre-programmed DX158 microcontroller — no coding required, just solder and go
• 5V DC power via Android (Micro-USB) port or 1.3mm DC socket — works with any standard 5V USB charger
• 3 control buttons: pattern switch (S3), slow down (S1), speed up (S2)
• Replaceable LEDs — swap in any color LEDs you like (observe polarity: anode up, cathode down)
• Great for learning circuit assembly, soldering technique, and microcontroller-driven LED matrix design

Circuit & Assembly Notes

• All polarized components (LEDs and microcontroller) must be installed in the correct orientation — do not reverse polarity
• All LEDs are installed with the positive (anode) side up and negative (cathode) side down
• C1 filter capacitor is optional and not included — its absence does not affect kit performance
• The microcontroller program is pre-burned — no programming knowledge needed

Frequently Asked Questions

Q: Do I need to program the microcontroller in this LED windmill soldering kit?

A: No programming is required. The DX158 microcontroller comes pre-programmed with all 9 animations. Simply solder all the components correctly, power it via a 5V USB charger, and the display will run automatically.

Q: What power supply do I need for this 43 LED DIY electronic kit?

A: The kit runs on 4–5V DC. It includes an Android (Micro-USB) power socket by default, so any standard 5V USB charging head or power bank will work. It is also compatible with a 1.3mm small DC barrel socket if you prefer that interface.

Q: Can I change the LED colors in this DIY soldering kit?

A: Yes! The LEDs are standard through-hole components and can be replaced with any color LEDs of your choice. Just make sure to observe the correct polarity — the anode (positive leg) goes up and the cathode (negative leg) goes down on the circuit board.

Q: Is this LED windmill kit suitable for beginners?

A: This kit is best suited for individuals who already have some experience with soldering and basic electronic circuits. Complete beginners may find it challenging. It makes an excellent practice project for intermediate hobbyists, students in electronics courses, or anyone building their soldering skills.
