• 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.
• 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 of NE555 is continuously added to the 14th pin of CD4017.
• 【speed adjustable】Adjust the R4 to adjust the speed of the LED light.
