Fire alarm using ic 555 and germanium diode dr 25?
A germanium diode controls the movement of electricity; arrows on the circuit depict which way, the 555 timer IC a unified chip capable of alarm and multivibratior functions. A fire alarm can built using these two parts plus resistors, capacitors, transistor, speaker, printed circuit board and 9v battery.
How can the flow of electric current be altered or modified?
The flow of electric current can be altered or modified by changing the voltage, resistance, or by using devices like switches, resistors, capacitors, and transistors in an electric circuit.

What is an ir detector?
In IR (InfraRed) detector is a circuit that receives an infrared input, either in an alarm or as a heat sensing device. In an alarm circuit, using an infrared beam rather than a laser has both advantages and disadvantages. Passive heat sensors rely on a general increase in temperature to identify a likely source, e.g. an animal, person, or vehicle engine.
