About Project
Basically, a microphone is a sound sensing transducer, which primarily transforms sound energy into electrical energy, so with the help of this sensor, we have to sound as a changing voltage.
Working is followed basically in four ways such as: Filtration, Amplification, Analog-digital conversion and programming to toggle the LED.
Whenever there is sound, the MIC strikes it up and transforms it into voltage, direct to the magnitude of sound. So for a higher sound, we have a greater value and for the lower sound, we have a deeper value. This value is first filled to the High Pass Filter for the process of filtration.
Then this refined value is filled to the transistor for amplification and the transistor gives the amplified output at the collector. This collector signal is supplied to the ADC0 channel of the UNO, for Analog to Digital conversion.
