If I waste my time teaching you (I am not a teacher) then you won't learn anything.But, can you elaborate the flow step by step cause as you can see I'm still new to this circuit thing.
Description:
This is a simple circuit in which the glowing LED can be switched OFF just by a puff. A condenser mic (M1) is used to sense your puff. When the push button S1 is pressed, the transistors Q2 and Q3 wired as latching pair gets activated and drives the LED to glow. The LED remains in this condition. When you puff on the condenser mic, the sound pressure is converted into a voltage signal at its output. This voltage signal will be amplified by the transistor Q1.Since the collector of the Q1 is coupled to the emitter of the latching pair, the pair will stop conducting when ever there is a signal from the condenser mic due to puffing and the LED will go OFF. The push button switch S1 has to be pressed again to switch the LED ON.
I suspect that Electronic Novice who started these identical threads is the same person as McFLY who asks the same kind of questions.
They both registered on the same day.
The original circuit is still at www.redcircuits.com/Page122.htm and C1 is also 100pf.The circuit by Circuitstoday.com does not work.
The main problem is the 100p on the base of the first transistor.
It should be 100n.
