Puff to OFF LED circuit
This circuit features an LED that can be turned off with a puff of air. A condenser microphone (M1) detects the puff. When the push button switch S1 is activated, transistors Q2 and Q3, configured as a latching pair, are...
led How should I build this circuit
The LED operates at 3V, and based on information available online, a blue LED typically supports a maximum current of 0.03A. Given the available current from the USB source, the intention is to construct a parallel circuit. However, the last...
555 circuits
The Switchgate is a simple dual gate circuit based on a 556 timer configured in monostable mode, featuring a trigger input that activates two switches. The outputs of the monostables are also available individually. Recent research has led to the...
HEE HAW ELECTRONIC SIREN
The oscillator based on IC2 generates sound, with its output linked to the base of TR1, which amplifies the signal to drive the speaker. Resistor R4 is included to limit the current through TR1 to a safe level. The oscillation...
