Kit name: NE555+CD4017 Water lamp kit/spare parts Power supply voltage: 2.5-14.5V PCB size: 5.4cm*2.1cm PCB thickness: 1.6mm Circuit principle:

This kit is mainly composed of a clock generator circuit and a decade counter circuit, a self-excited multivibrator with NE555 as the core. The power supply is charged to the capacitor C1 through R2,R3,R4, when C1 is just turned on At the beginning of charging, pin 2 of NE555 is still at a low level, so pin 3 of the output end is at a high level. When the power supply is charged from R2,R3,R4 to C1 to 2/3 of the power supply voltage, the level of pin 3 of the output end changes from high Low,NE555 internal discharge tube conduction, capacitor C1 through R4,R3,NE555 7-pin discharge, until the voltage at both ends of C1 less than 1/3 power supply voltage,NE555 3-pin level from low level to The high level.C1 is charged again, and this cycle creates an oscillation. The charging time is 0.695(R2+R3+R4)C1, the discharge time is 0.695(R4+R3)C1, and the vibration can be controlled by adjusting R4 The output frequency of the oscillator, the clock oscillation signal of NE555 is constantly added to the 14 pin of the CD4017, and 10 leds are connected to the 10 outputs of the CD4017 The end produces a high level in turn under the action of the clock signal, and D1--D10 are lit successively, thus forming the water lamp effect. Adjust R4 to adjust the flow speed of the LED light. List of parts:

The line layout is compact and regular, with good electrical insulation and mechanical stability, and can maintain stable performance under different temperature and humidity environments to ensure accuracy and reliability.

In circuit design, carefully planned lines are like precision transportation networks, and lines of different widths and spacings undertake different currents and signals transmission tasks respectively. The key signal lines are impedance matching processing, which greatly reduces signal reflection and attenuation and ensures the stable transmission of high-frequency signals.

All kinds of electronic components are soldered on the circuit board, and the solder joints are full, round, and firm and reliable. Core components like chips are perfectly connected to the circuit board through fine packaging processes to achieve high-speed data processing and interaction.

This circuit board has a wide range of responses in many fields. Whether in the industrial control field that requires extremely high stability or consumer electronics field that pursues extreme performance, it can provide solid guarantees for the stable operation of the equipment with its excellent design and reliable performance, and help various electronic devices play a powerful role.
