Does anyone have suggestions for detecting sound with a sound sensor module to display on a MAX 7219 display with more illuminated dots for higher sound levels? I could use assistance with both the wiring and coding.
Do you mean an audio visualizer, with different bars symbolizing different ranges in the frequency and the height symbolizing strength/volume?
These are the components I’m using
Sound Sensor
Max module
My World's Simplest Lighting Effect should get you started.
...You don't need the bias circuit. Use the analog output from the microphone board and it should already be biased. If you are using the Arduino Uno or one of the similar Arduinos you can just wire-up the sound sensor and the program should blink the built-in LED.
Do you have any documentation? ...I don't recommend buying from "unknown" 3rd-party Amazon suppliers that don't provide documentation.
I found a little information about the sound sensor. The MAX7219 is an LED driver chip and it's well documented by the manufacturer but that doesn't tell you anything about the LED assembly. 
Adafruit sells lots of well-documented LED matrcies/displays and they have lots of tutorials & example projects.
