Hi guys, I have an analog signal going to the arduino and I need to detect peaks. My project is about detecting values of noise in a room. I connected microphone with an amplifier and this signal is going to my Arduino, the problem is, that analogRead is giving me ,,random" values varying a lot. I …

TeresaH:
how did you decide these values?

Each sample takes about 100usec.
500 samples will capture the full wave of 20Hz.
