5Pcs Diy Analog Electronic Candle Production Kit Ignition Control Simulation

Description : CD4013 is a dual D flip-flop consisting of two identical and independent data flip-flops. When the rising edge of the clock is triggered, the logic level added to the D input terminal is sent to the Q output terminal. Setting and resetting are not related to the clock, but completed by the high level on the set or reset line, respectively. This circuit uses a D flip-flop in the double D flip-flop, which is connected to RS flip-flop. When the power supply is switched on, the differential circuit composed of C2 and R2 generates a high-level differential pulse to the IRD end of je 1, forcing the circuit to reset, and the low-level output of the first end is sent to the base of Q4 transistor, Q4 is cut off, and the light-emitting diode is not bright. When the lighter is close to 940 infrared receiving diode, the infrared diode is in reverse breakdown conduction, the resistance value suddenly decreases, the base of Q1 presents a low level state, the transistor Q1 is turned on, Lees meer over de 5Pcs Diy Analog Electronic Candle Production Kit Ignition Control Simulation van huismerk in de productgroep elektronica
