sound sensor

Overview

A sound sensor was used. I originally wanted to look for it on the open source platform, but found that it was not available, so I made some changes and designed this sound collection module by referring to a certain product.

1. Collect audio signals as analog quantities

2. Convert analog quantity to digital quantity through comparator

Supply voltage 3.3V-5V
