This research is intended to be used to design a circuit that converts any sound to light, it is an electrical circuit with a Sound sensor, when it hears the sound wave, the sensor converts that sound wave to a certain volts (electrical wave), and the electrical wave runs through the circuit and then turns on the light and turns off the light when the sound is absent, It is very useful in several areas and can be used anywhere so the idea Is that we use energy when we want to and limit the use of no need energy ,it can be used whether at home, mosques and especially on streets to save energy wasted by unnecessary turned on lights, and it is inexpensive in relation to its benefits.

The idea of designing a microphone is similar, the sound of human being passes through the circuit after it is converted to electrical signal and then it is magnified to a higher level of sound signal, here are some other related designs.

[...] R The IC555 Comparator component Design Specifications: We are our design component specifications in details, component name, its specifications, function (role in the circuit) and a picture of it. Stages of building the circuit: Final design: Method of Operation The sound sensor will sense the noise made by cars on the street and then convert it to a signal, then the resistor which is connected to the negative side of the sensor and the positive side of the battery that is connected to the positive side of the sensor. [...]


[...] Must not exceed 1000SR. It must have the ability to work in many places. Black Box Analysis: A black box is a graphic representation of the system or object being designed, with inputs shown entering the box on its left hand side and outputs leaving on the right hand side, this tool obviously helps relate inputs to outputs and the transformation between them. Figure This is our black box analysis for our project, showing inputs and outputs that the design can take. [...]


[...] The transistor will make the signal bigger because the signal that always enter it is very small so that's why we put two transistor The capacitor with 0.1 µF will block the DC voltage and only let the signal that came from the sound to enter The IC555 contain an amplifier works as a comparator, if the voltage enter the positive side less than in negative side, the output voltage will equal zero, and if the voltage that enter the positive side greater than the one on the negative side so the valuable voltage will be it, that's mean the IC will pass it to the light pulp.
