Lesson 7 – Arduino Microphone

 

Lesson 7 – Arduino Microphone Movie

In this example I will show how to work with the Microphone from Arduino kit.

When there is a noise in Microphone a Led will light, when there is a noise again it will be turned off, and each time the led will change its light (on/off).

I will also explain about the Microphone board pins and behavior (I will include some oscilloscope pictures)
