Description

Amazon 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 signal of NE555 is continuously added to the 14th pin of CD4017. 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. Mainly composed of clock generation circuit and decimal counter circuit. The self-excited multivibrator with NE555 as the the power supply charges capacitor C1 through R2, R3, R4. When C1 starts charging, the 2 pin of NE555 is still at low level, so the output pin 3 is high level. When the power supply is charged to the Adjust the R4 to adjust the flowing speed of the LED light.
