Two Side Weld – F
1. Circuit Function Principle:
1).After power on,NE555 and peripheral circuits form a multivibrator.The oscillation frequency is mainly determined by R1-R5 and C1.Adjusting the value of RC can change the oscillation frequency and thus change the flow rate (components that change the parameters need to be prepared by themselves).
2).The oscillation signal of the oscillator is output from the NE555 pin 3 and sent to the count input terminal (pin 14) of the CD4017.When a pulse arrives,the LED11 lights up once,and the high level of the Q0-9 output of the counter moves 1 bit in turn ,To light up the corresponding light-emitting diodes,thereby creating a feeling of running water.
3).After the count is full,it starts counting again from the beginning,so that the circuit continues to cycle,and the CO terminal outputs a pulse every cycle,and the transistor VT1 is driven to control the LED12-LED15 to light up once.
