ICSK050A DIY Kits Clap Switch Suite Sound Sensor DIY Electronic Production

Clap switch kit is composed of a number of resistors, capacitors and transistor amplifier circuit. Circuit is simple, welding easy, inexpensive, and can be widely used in voice-activated switch.

This circuit mainly by the audio amplifier circuit and a flip-flop circuit.

Q1 and Q2 form a secondary audio amplifier, an audio signal received from MK1 C1 is coupled to the base of Q1, the amplification is fed directly from the collector to the base of Q2, the collector of Q2 to obtain a negative square wave with to trigger the bistable circuit. R1, C1 limit the frequency response of the circuit for the high sensitivity range of about 3kHz. When the power is turned on, the state of the bistable circuit is off Q4, Q3 saturated, D3 does not shine. When MK1 to a control signal output after the two-stage amplification of a negative square wave, after the differential processing by the negative spike D1 added to the base of Q3, the circuit rapidly inverted, D3 is illuminated. When MK1 again received control signal, the circuit took place flip, D3 extinguished. The board reserved for external control devices connected to terminals J1, can be a voice for other devices connected via J1 relay. (When connected to both ends of the relay coil relay to be anti and a diode)

This circuit uses a DC 5V power supply, turn off the machine when the LED current of 3 mA, the LED lights up the whole current of 6mA.

VCC: Connect 5V power supply positive (according to the relay voltage)

GND: Connect 5V power supply negative
IN: relay module signal trigger (low level active)
High and low meaning:
High-level trigger refers to the VCC side of the positive voltage and the trigger side of a trigger
When the trigger side has a positive voltage or to reach the trigger voltage, the relay is sucked.
Low-level trigger refers to the use of GnD side of the negative voltage and the trigger side of a trigger
When the trigger side OV voltage or voltage is low to trigger, the relay is pulled.

Arrow pointing at the two pads, need to use wire links
As shown below:

Why change it:
This is when the effect of the wiring board, the figure where the red circle there was a small mistake, take the line did not come on the pads, a little bit worse, make friends, their answer it by the above method.
