Product description format_size zoom_out zoom_in

The circuit uses an electret microphone of the 97xx . Because the signal from the microphone is quite low, a microphone amplifier is assembled on transistors Q1 and Q2. From the microphone amplifier, the signal goes to the flip-flops Q3 and Q4, with each pop, the trigger output changes its state, the transistor Q4 opens or closes. This is accompanied by LED indication.
Using this circuit, you can control lighting or any other load.To do this, you need to install a relay on the board output through which the load will be powered.
Board size 50 * 28mm.
