Description of the circuit principle: U1: CD4060 is a 14-level binary frequency counter with an oscillator,R14, R15, RP1, C1 and U1 9, 10, 11 pin of the circuit composed of the oscillator, the oscillation frequency can be adjusted by RP1. At the beginning of power-on, the timing clock generator is reset by the capacitor of U1-12 pin, and each output stage is low potential. With the oscillation of the oscillator, the Q4-Q14 of the output U1 is gradually output in binary form, and the three groups of light tubes are also on and off with the change of the high and low level of the output terminal. When a certain end outputs high voltage, the corresponding group of light tubes is off, and the output of low voltage, the corresponding group of light tubes is on. Triode Q1, Q2 and Q3 play a driving role, and D1, D2 and D3 play a cyclic reset role. Q5, Q6, and Q7 of U1 are reset at high voltage.
