The circuit is mainly composed of a pulse generator and a decimal counter circuit.
The pulse generator consists of NE555 and peripheral components. The multi-vibrator is composed. When the button S1 is pressed, Q1
is turned on, and the NE555's 3 pins output pulses. The 10 outputs of the CD4017 alternately output high-level driving 10 LEDs to
rotate. After releasing the button, Q1 will not be cut off immediately due to the presence of capacitor C1. As the voltage across
C1 decreases, the conduction procedure of Q1 gradually decreases, the frequency of the output pulse of 3 pin becomes slower, and
the frequency of LED movement also follows. Slow down. Finally, when the C1 discharge is over. When Q1 is cut off, the NE555's 3
feet no longer output pulses, and the LED stops moving. A "winning" process was completed. R2 determines the speed of LED
movement, and C1 decides the time to wait for the "winning".
