Principle introduction: U1: CD4060 is a 14 stage two frequency division counter with oscill-ator. R14,R15,RP1, C1 and circuits in pins 9, 10 and 11 of U1 forman oscillator. The oscillation frequency can be adjusted by RP1.At the beginning of power on, the timing clock generator is first reset by the capacitor of u1-12 pin, and each output stage is low potential. With the oscillation of the oscillator, q4-q14 of the output terminal U1 is output in binary form, and the three groups of light-emitting tubes are also on and off with the change of the high and low levels of the output terminal. When a terminal outputs a high level, the corresponding group of light-emitting tubes is off, and when the output level is low, the corresponding group of light-emitting tubes is on. Triodes 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 level.
