Clap Switch Kit Electronic DIY Kit Electronic Learning Kit

Feature:

Type: HY Working voltage: 5V PCB: 28 x 49mm

How it works:

Q1 and Q2 form a secondary audio amplifier circuit from MK1 audio signals via the C1 coupled to the base of Q1, after amplified by a direct feed to an Q2 collector base, the collector of Q2 obtain a negative square wave to trigger the bistable circuit. R1, C1 circuit frequency response is limited to 3kHz for high sensitivity range. When the power is switched on, bistable circuits status is Q4 closing, Q3 saturated, D3 is not lit. When MK1 received control signals, after two amplifier outputs a negative square wave, after the differential processing, the negative spike through D1 added to the base of Q3, made the circuit rapidly inverted, D3 is illuminated. When MK1 received control signals again, the circuit overturned again, D3 is off. On the circuit board reserved the external control device terminals J1, can voice-activated with other equipment via J1 connection to relay. (When connected to the relay, both ends of the relay coil need to be added a diode)

Note:

We don't offer any manuals, only has schematic, please note about this before you buy it, sorry for the inconvenience.
