Question

Can you rephrase this paragraph? or make it like your own words? So that it doesnt look like copy and pasting? Also this is a description of the project, what is the project all about, how does the project work. Project is about dancing led's link: https://circuitdigest.com/electronic-circuits/simple-led-music-light

In this Simple LED Music Light Circuit, condenser mic picks up the sound signals and converts them into voltage levels. These voltage signals are further fed into R-C filter or HIGH PASS filter (R2 and C1), to eliminate the noise from the sound. Further a NPN transistor (Q1- BC547) is used to amplify the signals, from the High Pass filter. Then finally these music signals are given to the array of four transistors. Transistor in this array works as amplifier, and glows the four LEDs according to the sound pattern. This generates a very interesting sequence of dancing LEDs which follows the beats as per their intensity or pitch. We can also add more LEDs with transistor to make it cooler.

We can adjust the sensitivity of MIC by changing the value of R2 and C1, by using the formula for R-C filter:
F = 1/ (2RC)
F is the cut off frequency, means filter only allow frequency above than F. It can be easily deduced that more the value of RC, less the cut off frequency and higher the sensitivity of MIC. And higher the sensitive of circuit means MIC can pick low volume sounds, hence LEDs can glow on low pitch music also. So by adjusting its sensitivity we can make it less sensitive to reacts only on high note beats or we can also make it more sensitive to react on every little beat in the music. Here we have set its sensitivity at moderate level.

Condenser Mic should be connected properly in the circuit, according to its polarity. To determine the polarity of MIC one should look at mic terminals, the terminal which have three soldering lines, is the negative terminal.

Transistor BC547 is a NPN transistor, which is used as a Amplifier here. NPN transistor acts as a open switch when there is no voltage applied on its Base (B) and it acts as closed switch when these is some voltage at its base. Generally 0.7 volt is enough to get it fully conducted

Explanation / Answer

Circuit shown is that of simple music light. In this circuit, condenser mic acts as a transducer (transducer is part of an electronic system which converts signals acquired through nature into electrical signals) picks up the sound signals and converts them into equivalent voltage levels. The voltage signals are passed into R-C filter or HIGH PASS filter (R2 and C1). Here the noise and other disturbances are eliminated. A NPN transistor (Q1- BC547) is then used to amplify the signals. Finally, the electric version of the music signals are given to the array of four transistors. These transistors work as an amplifier, and glow the four LEDs according to the sound pattern. As a result, we have interesting sequence of dancing LEDs, which follows the beats depending on their intensity or pitch. It is also possible to add more LEDs with transistor to for cooling.

The sensitivity of the mic can be adjusted by changing the value of R2 and C1, by using the following formula for the RC filter
Fc = 1/ (2RC) Here, F is the cut off frequency of the high pass filter which indicates that only frequencies above the value of Fc are allowed .We can see that Cut of frequency is inversely proportional to the time constant T = RC. Hence more the value of time constant lesser is the cut off frequency of the RC high pass filter and higher is the sensitivity. Higher sensitivity means MIC will be able to pick out low volumes since the cut off frequency of the signal is low due to which LEDs can glow on low pitch music. So by adjusting sensitivity we can make the mic less sensitive i.e it will react only for high note beats. When more sensitive it will react on every little beat in the music. In our circuit, we have set the sensitivity at moderate level.

Condenser Mic should be connected according to its polarity. Observe mic terminals in which the terminal having three soldering lines, is the negative terminal.

Transistor BC547 is a NPN transistor, which is used as an Amplifier here. It acts as an open switch when there is no voltage applied on its Base (B) and it acts as closed switch when these is some voltage at its base which is about 0.7V
