DIY Electronic Kit 80 LED Circular Pentagonal Star Flowing Water Lamp Kit Microcontroller Electronic Production Skills Practice

The products which are suitable for electronic enthusiasts to study and repair circuits. We only guarantee that the products are in good condition before delivery, and cannot guarantee 100% success after installation. The installation of the circuit requires the buyer to have experience in the circuit, please read the product description carefully before payment.Kind reminder: The circuit board color of this kit is black or green, randomly sent. If you mind, please purchase with caution.Function DescriptionThis circuit is an innovative design for dynamic electronics. After being powered on, a circular five pointed star pattern consisting of 80 LEDs is formed. After turning on, the circuit lights up in sequence, and then flashes multiple times with full brightness. Finally, multiple patterns are presented in sequence, such as an inner edge less shape, an outer five pointed star, a regular five pointed star, a circle, and a circular five pointed star. Press S2 to adjust the flow speedIntroduction to Circuit Principles80 LEDs are connected to a dedicated microcontroller DX158 through a combination of rows and columns, and are scanned and driven to light up in the desired way through the microcontroller program. The microcontroller program in this kit has been burned and welded to produce the desired effect. 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, and the kit provides an Android Shen source socket by default, without a small DC socket. Any 5V charging head can be used for power supply. S1 is the power switch, and C1 is the backup filter capacitor. It is generally not installed and is not provided in the kit, which does not affect the effectiveness of use. 3. Installation precautions: All light-emitting diodes and microcontrollers have polarity components. Be careful not to install them upside down. If you need other color effects, just replace the LED.
