Key features

  • CD4017: 10 LEDs are connected to the 10 output terminals of CD4017, which alternately generate high levels under the action of the clock. D1-D10 are sequentially illuminated, forming a water light effect
  • NE555: A self-excited multi harmonic oscillator with NE555 as its core. When the power supply starts charging capacitor C1 through R2, R3, and R4, output pin 3 is at a high level. When charged to 2/3 of the power supply voltage, the internal discharge tube of NE555 conducts
  • Working Principle: The charging time is 0.695 (R2+R3+R4) C1, and the discharging time is 0.675 (R4+R3) C1. R4 can be adjusted to control the output frequency of the oscillator. The clock oscillation signal of NE555 is continuously added to the 14th pin of CD4017
  • Adjustable Speed: The flow speed of the oscillator LED light can be adjusted by adjusting R4 to customize the light according to your preferences, suitable for electronics kit circuit experiments and decorative lighting projects
  • Easy to Use: The DIY soldering practice kit mainly consists of clock generation circuit and decimal counter circuit, suitable for electronics enthusiasts and beginners
