DIY Kit Sound Control Switch KIT Clap Control Electronic DIY Fun Making Kit Electronic Training Kit
Kit features: Take a shot, LED light, and then take a hand, the lights off, so the cycle.
Features: high sensitivity, about 4 meters clapping can control.
Working voltage: 3-5.5V
PCB size: 27*49mm
Working principle:
Q1 and Q2 two level audio amplifier circuit, the audio signal received by MK1 by C1 coupled to the Q1 base, the base by
the collector directly fed to Q2 amplification, a negative square wave at the collector of Q2, used to trigger bistable
circuit. R1 C1, the circuit frequency response for high sensitivity limit in the range of about 3kHz. When the power is
switched on, the state of the bistable circuit is Q4, Q3 saturation, D3 is not bright. When the MK1 receives the control
signal, after two stages of amplification, the output of a negative square wave, after the differential treatment of the
negative pulse through the D1 to the base of the Q3, so that the circuit quickly turned, D3 is lit. When the MK1 is
connected to the control signal, the circuit turns again and the D3 goes out.
Note: the electret MIC which is connected with the outer casing is a cathode, light emitting diode and two feet for
electrolytic capacitor anode (positive negative short), a triode to real direction of installation, resistance and non polarity
of ceramic capacitors.
