Function Description
After being powered on, 43 LEDs dynamically display various patterns, and 9 animation playback switches are achieved through the screen switching switch S3, including forward windmill, reverse windmill, rotating petal, rotating pendulum, rotating sheep horn, petal blooming, snowflake formation, concentric diffusion, and rotating ellipse. Press S1 to slow down and S2 to accelerate.
Introduction to Circuit Principles
43 LEDs are connected to a dedicated microcontroller DX158 through a combination of rows and columns, and are scanned and driven to light up as needed through the microcontroller program. The microcontroller program of this kit has been burned and can produce results after welding. DC1 is a power socket that is compatible with both a 1.3mm small DC socket and an Android interface power socket. It can be powered by 4-5V DC. The kit provides an Android socket by default, without a small DC socket, and can be powered by any 5V charging head. C1 is a backup filter capacitor that generally does not need to be installed and is not provided in the kit, which does not affect the effectiveness of use.
Installation precautions:
All light-emitting diodes and microcontrollers have polarity components. Be careful not to install them upside down. If other colors are needed, simply replace the LEDs (note: all LEDs on the circuit board are installed in the up positive and down negative directions).
