Product Introduction:
This kit mainly consists of a clock generator circuit and a decimal counter circuit. It is a self-excited multivibrator with NE555 as the core. The power supply charges capacitor C1 through R2, R3, and R4. When C1 first starts charging, the two pins of NE555 are still at a low level, so the output terminal three pins are at a high level. When the power supply charges C1 to 2/3 of the power supply voltage through R2, R3, and R4, the output terminal three pins level changes from high to low. The internal discharge tube of NE555 is connected, and capacitor C1 is discharged through the seven pins of R4, R3, and NE555, Until the voltage at both ends of C1 is lower than 1/3 of the power supply voltage, the 3-pin level of NE555 changes from low level to high level again C1 recharged again, and this cycle formed oscillation. The charging time is 0.695 (R2+R3+R4) C1, and the discharge time is 0.695 (R4+R3) C1. Adjusting R4 can control the output frequency of the oscillator. The clock oscillation signal of NE555 is continuously added to the 14 pins of CD4017, and 10 LEDs are connected to the 10 output terminals of CD4017. When the 10 output terminals of CD4017 take turns generating high levels under the action of the clock signal, D1 to D10 are sequentially lit, forming a flowing light effect
