Hi, I'm starting this project and would like to know from you if I'm on the right track or not?
25x KY-038 sound sensers
Arduino with nrf24l01
Android app that displays 25 lights-
green when noise
red when silent
I can't seem to find anything on creating a android app as a display for what state the sensors are at besides serial displays (not what I want). Only to use app as a remote?
