off position.\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eThe audio signal enters from the microphone to transistor 1 through capacitor 2 entering variable resistor 1 allowing sensitivity adjustments.\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eThe collector of transistor 2 is connected through capacitor 3 and 4 creating a flip-flop sector comprising of transistor 3 and 4 both taking turn functioning to the signal transmitted by the microphone.\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eThe transmittal of an audio signal through transistor 1 and 2 causes the collector of transistor 2 to be amplified creating a momentary low voltage while current at the base of transistor 4 is drawn through diode 2 and capacitor 4 to ground at collector transistor 2 making transistor 4 stop inducing current.\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eThe higher voltage will cause transistor 3 to draw current through the base of transistor 4 and ground causing transistor 3 to work in place of transistor 4.\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eAt this point the relay will release the contact face so the LED will be turned off.\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eTransistor 4 will be inactive until an audio signal is present to cause transistor 3 to stop induction and then transistor 4 will start functioning.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\u003c!--M_96613636\/--\u003e\u003clink nonce=\"7XHXAj+qlFTeqndFv55Kvw==\" rel=\"modulepreload\" crossorigin=\"\"
