NE555 + CD4017 Water Flowing Light LED Module DIY Kit This is NE555 + CD4017 Water Flowing Light LED Module DIY Kit. It has a double-sided board with a surface mount and a through-hole configuration. It is designed for users with advanced soldering skills. You must solder some components on the top surface and some components on the bottom side of the board. The module has a very simple assembly process that will take anywhere between 30 minutes to an hour. This kit is mainly composed of clock generation circuit and decimal counter circuit. The NE555 is the core self-excited multivibrator. The power supply charges the capacitor C1 through R2, R3 and R4. When C1 starts charging, the NE555 2 pin also At low level, the output pin 3 is high. When the power supply is charged to C2 to the 2/3 power supply voltage through R2, R3, and R4, the output pin 3 level changes from high to low. NE555 internal discharge tube guide Pass, capacitor C1 is discharged through pin 7 of R4, R3, NE555, until the voltage across C1 is lower than 1/3 of the power supply voltage, the level of the 3 pin of NE555 changes from low level to high level. C1 is charged again. This cycle forms an oscillation. 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. Adjust the R4 to adjust the flow speed of the LED light.
