LED Chaser Light Module 2 Pcs Electronic Light Kit for Electronic Circuit

WORKING PRINCIPLE: The charging time is: 0.695 (R2+R3+R4)C1, the discharge time is: 0.695 (R4+R3)C1, the R4 can be adjusted to control the output frequency of the oscillator, and the clock oscillation of NE555 is continuously added to the 14th pin of CD4017 10 LED: Ten LEDs are connected to the 10 outputs of the CD4017. When the 10 outputs of the CD4017 alternately generate a high level under the action of the clock signal, D1--D10 are sequentially illuminated to form a water-light effect SPEED ADJUSTABLE: The flowing light is adjustable, by adjust the R4 to adjust the speed of the LED light NE555 The self-excited multivibrator with NE555 as the the power supply charges capacitor C1 through R2, R3, R4. The water flowing light is mainly composed of clock generation circuit and decimal counter circuitmade of high quality electronic component, has a long service life
