This circuit simulates a real candle, lit with fire, and blown out with a mouth. Light up and play the "Happy Birthday to You" song, stop playing the music when it blows out.

1>.Product Name:DIY Kit Analog Electronic Candle Light
2>.Work Voltage:DC 5V
▲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-level differential pulse, then outputs it to the RST terminal of IC1, forcing the circuit to reset. The Q terminal outputs a low level, and outputs to the base of the triode VT5 and VT6. VT5. VT6 is cut off, the LED is not lit, and the buzzer does not ring.
▲When the thermistor Rt is burned with a lighter (the burning time is too long and the thermistor is easily burned out), the resistance of R1 suddenly becomes small, showing a low resistance state.
▲The triode VT1/VT2 is turned on successively (Rp1/Rp2 can be separately adjusted for VT1/VT2 on-time), the high-level pulse generated is output to the SET terminal of IC1, the Q-end is turned to a high level, and the output is applied to the base of the transistor VT5/VT6, and the triode VT5/VT6 is turned on.
▲LED turn ON, the buzzer plays the "Happy Birthday to You" piece. This process is equivalent to lighting the candle with a match. At this time, even if the lighter leaves the thermistor Rt, the state of the circuit does not change.
▲When the wind blows toward the microphone M1, the audio signal output by the microphone M1 is output to the base of the VT3 through C3, and the VT3 is turned on.
▲Because the resistance of R5 is relatively large, the collector potential of VT3 drops very low, the base potential of PNP transistor VT4 is very low, VT4 is turned on, and the high level pulse is output to the RST terminal of the flip-flop.
▲The trigger is reset, the Q terminal changes from high level to low level, VT5/VT6 is cut off, the light emitting diode is off, and the buzzer stops playing the "Happy Birthday to You" music, realizing the simulation effect of "wind blowing out".
1>.Complete the correct installation according to ‘Installation Steps’.
2>.Connect 5V power supply.
3>.Use a lighter to burn the thermal sensor about 2second(Can not for more time.Otherwise it will damage the sensor)
4>.LED will turn ON and Buzzer playing ‘happy birthday to you’.The buzzer can only simulate playback, the quality of the voice is not very good, please note.
5>.Blowing towards the microphone, the LED will go out and the buzzer will stop playing.
1>.User needs to prepare the welding tool first.
2>.Please be patient until the installation is complete.
3>.The package is DIY kit, not finished products.
