Description:
This circuit simulates the use of real candles, is lit with fire, and blown out with a mouth. Light up and play your happy birthday song, stop playing the music when it blows out.
The analog electronic candle has the simulation of match ignition and wind blowout. The original design comes from the real life plot: the use of the candle, the circuit can be used for the birthday party after the transformation. This kit is improved on the basis of single lamp, the difficulty is increased, the number of lanterns is increased to 13, and the birthday music function is added, and the simulation is stronger.
Principle:
This circuit uses a D flip-flop to form an R-S flip-flop. After the power is turned on, the differential circuit composed of R7 and C4 generates a high voltage differential pulse to be applied to the RST terminal of IC1, forcing the circuit to reset, and the Q terminal outputs a low level to the base of the transistor VT5, VT6, VT5, VT6 cutoff. The LED is not lit and the buzzer does not ring. When the thermistor RT is burned with a lighter, the resistance of R1 suddenly changes to a low resistance state, and the transistors VT1 and VT2 are turned on successively (RP1 and RP2 can respectively adjust the on-time of VT1 and VT2), and the generated high level is generated. The pulse is sent to the SET terminal of IC1, the Q terminal is turned to a high level, and sent to the base of the triode VT5 and VT6. The triode VT5 and VT6 are turned on, and the triode and the buzzer play the song. This process is equivalent to using a match point.Light the candle, even after the lighter leaves the thermistor Rt Does not change the state of the circuit. When using a mouth to blow an electret microphone At MI, the buccal signal output by the electret microphone MI is sent via C3.To the base of VT3, trigger VI3 to turn on. Comparison of resistance values of R5Large, so the collector potential of VT3 drops very low, PNP type triode The base potential of VT4 is also very low, VT4 is on, high level pulse Send to the RST terminal of the trigger. Trigger reset, Q terminal changes from high level Low level, VT5, VT6 cut off, the light emitting diode is off,The buzzer stops playing and I wish you a happy birthday song.The simulation effect of the fire extinguished. The circuit has a wide supply voltage range.
Parameter:
Work voltage:DC 4V-10V
