Crowbits-Microphone

What is Crowbits-Microphone?

Crowbits-Microphone is an analog input module that can be used as an ear for your circuit, it detects the sound from the environment.

How does it work?

The microphone module is a transducer that converts acoustic pressure waves to electrical signals. The interface of the microphone is an analog interface, it continuously outputs an analog signal in the range of 0 to 1023.

1. When the microphone detects the sound, the operational amplifier circuit on the board amplifies the sound signal, then transmits this signal to the output modules, such as a buzzer, then we will hear the sound.

Use cases

For example, The microphone module can be used to control the brightness of an LED. The more noise you make - the brighter the LED is.
