Hello Everyone,
I am new to Arduino. This is the first time I am trying something with Arduino.
I am trying to do a 7 band spectrum analyser with electret mic and msgeq7 with Arduino UNO. I first tried connecting the ledstrip and was so excited when it worked (although its very simple, lol) but when I connect the mic and msgeq7 to Arduino and read analog signal, it gives same values in silence and when there is music playing as well. Even when I read analog signal from a different pin which is not connected to anything, it still reads the same values. So, I am assuming that there is some problem in the circuit or something.
I have attached the schematic (I am not using the clock module, pin 8 on msgeq7 is not attached to anything. I am using only 1 msgeq7 as its only 7 band and not 14 band analyser. For audio input, I am using electret mic, the rest is all the same as shown in the attached diagram).
This is the output from serial monitor:
