Description: Working voltage: DC 5V Work effect: speed can be adjusted Size: 40 x 50mm Note: it is not soldering finished product, it is diy kit. Circuit principle:   The circuit is based on the control of the microcontroller, the microcontroller controls the vertical LED lit, so as to achieve the effect of a windmill rotation, you can change the speed of the windmill flashing through the button. Package included: 10 x DIY windmill training kit

Note: This is a DIY kit, you need to have some electronic knowledge and ability. SMD is unsoldered!! The kit has certain difficulty, please buy according to your own situation. Special note: According to some buyers feedback, CH340 TTL serial port cannot be used to download the microcontroller program, can only be used to the change words! Hardware parameters (error 2mm): Rotating motherboard long: 8.1cm Rotation display diameter: 9.2cm Side panel high: 7.5cm Side round monochrome 56 LED display Acrylic bottom box: 11 x 11 x 4.5cm (L x W x H) (excluding coil and the motor shaft) Features: 2 set of text scrolling cycle (It can store 850 characters in Chinese/English): Through the remote control can stop scrolling, you can edit the text displayed by the PC software. Clock and date display: Build-in backup battery, after power-down remains working, you can set the time by remote control or changing the word software calibration time, is very convenient! Image display: Can continuous scrolling display pictures, can be displayed static image alone, too! Select mode by remote control. Photos must be a 64 pixel wide, the pixels long can be 10-200. (It can store 30 photos, should be black character on white background's monochromatic photo) Memory mode: It will stay the mode when you shutdown (Note: Can only be one of the above three kinds of modes). Specification: Motor: 370 Power supply: 5V external power / USB 5V or you can use DIY battery (battery does not includes) If you need TTL serial downloader to send the changes content to the microcontroller, please use your own downloader, this kit does not includes downloader. Package includes: 1 x DIY Spherical Rotating LED Kit

Feature: Supply voltage: 4-5.5V Dimensions: 75 x 85mm Principle: This kit contains 32 LED arranged in a heart-shaped pattern, driven by the IO port (active low); Write program control IO port to high and low level, the LED lights off or on, forming a variety of patterns effects, especially when used at night, very dynamic. Circuit is divided into three parts: the minimum system circuits, power circuits, and heart-shaped lamp circuit; Connect power 4-5.5V, press S1 latch switch (this circuit design two power interface, easy to operate), the microcontroller begin to work, 32 IO ports each string limiting resistor and LED lights connected to VCC, which LED lights which IO port is low, which is fully controlled by the program; This kit has been programmed, after assembled can be connected to display all kinds of tricks. Installation Notes: Pay attention to polarity when installing light-emitting diodes and electrolytic capacitors, long legs is positive. Note the U port direction when you install the chip seat, the positive and negative power supply can not be wrong, otherwise it will burn the chip. The middle of plug socket is positive, the outside is negative. Package included: 5 x Heart Shape LED Flashing Kit Test photos, for reference only!
