Resistor Chip Arrays
Product name: 80LED Circular Pentagonal Star Light Plate Flow Light Electronic DIY Kit
Product Model: TJ-56-680
Supply voltage: 5V (DC power supply)
Board size: 75*75mmFunction description:This circuit is powered on 80 LEDs composed of a circular pentagram pattern, after switching on the sequential flow of water lit, and then fully lit many times gap blinking, and finally in order to present the inner pentagon, the outer pentagram, the positive pentagon, round, circular pentagram, and other patterns, the key S2 can be adjusted to the speed of the flowing lights.
Note: The product is DIY loose parts, you need to solder it by yourself.
Circuit diagram:80 LEDs are connected to a dedicated microcontroller STC8G1K08 through row and column combination, and are scanned and driven to light up as needed through the microcontroller program. The microcontroller program of this kit has been burned and after welding, the product effect can be displayed. DC1 is a small DC socket that can be powered by either 4-5V DC or any 5V charging head. S1 is the power switch, C1 is the backup filtering capacitor, which generally does not need to be installed and is not provided in the kit, which does not affect the effectiveness of use.
