Product Introduction:

This package is mainly composed of clock generation circuit and decimal counter circuit. The NE555 is the core of the self-excited multivibrator. The power supply is charged to capacitor C1 through R2, R3 and R4. When the C1 is started to charge, the NE555's 2 feet are still Low level, so the output 3 feet are high, when the power by R2, R3, R4 to C1 charge to 2/3 power supply voltage, the output 3 feet level from high to low, NE555 internal discharge tube conduction , Capacitor C1 by R4, R3, NE555 7 feet discharge, until the voltage at both ends of C1 less than 1/3 of the power supply voltage, NE555 3 feet level from low to high level.C1 again charge, So the cycle of the formation of oscillation.
Charging time is:(RS + R3 + R4) C1, the discharge time is: 0.695 (R4 + R3) C1, adjust R4 can control the output frequency of the oscillator, NE555 clock oscillation signal is constantly added to the CD4017 14 feet, 10 of the 10 outputs of the CD4017 are connected to 10 LEDs. When the 10 outputs of the CD4017 are rotated high by the clock signal, the D1 - D10 is illuminated in order to form a running lamp effect. Adjust R4 to adjust the flow rate of LED lights.
