Special Features

  • [ Components] Includes premium ne555 timer ics and cd4017 counters along with durable leds and resistors on compact 5.4x2.1cm boards. each 2-piece set comes with all required electronic components, allowing you to build two complete modules for comparison or different speed settings.
  • [Educational Diy Project] Ideal for electronics enthusiasts, students, and hobbyists to learn about timer circuits, counters, and led driving principles. the through-hole design is perfect for soldering practice and circuit analysis. complete with all necessary components for hands-on learning about electronic oscillations and digital sequencing.
  • [Adjustable Speed Control] Featuring a variable resistor (r4) that lets you easily customize the light chasing speed to create fast dynamic displays or slow graceful transitions. simply turn the potentiometer to change the oscillation frequency of the ne555 circuit, allowing complete control over your visual effects from rapid strobes to gentle waves.
  • [Dynamic Led Water Effect] This innovative kit creates a mesmerizing water-flowing light effect using 10 bright leds that sequentially illuminate under the control of the ne555 and cd4017 circuits. the smooth chasing pattern simulates flowing water, perfect for eye-catching displays, decorations, or educational demonstrations of electronic principles.
  • [ Timing Circuitry] At the heart of this module is the ne555 timer ic forming a self-excited multivibrator that generates precise clock pulses. these pulses drive the cd4017 counter which sequentially activates each led. the sophisticated circuit design ensures stable operation between 2.5-14.5v, making it versatile for various power sources.

Description

1. Mainly composed of clock generation circuit and decimal counter circuit.
2. The self-excited multivibrator with NE555 as the core, 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 2/3 power supply voltage through R2, R3, and R4, the output pin 3 level changes from high to low, and the NE555 internal discharge tube is turned on. The capacitor C1 is discharged through the 7-pin of R4, R3, and NE555. Until the voltage across C1 is lower than 1/3 of the power supply voltage, the level of the 3 pin of the NE555 changes from low level to high level. C1 is charged again, and the cycle forms an oscillation.
3. 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.
4. 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.
5. Adjust the R4 to adjust the ​ speed of the LED light.
