Arduino Voice Changer

Post by ElevationStudnt »

I am building the Arduino Voice Changer and have run into a slight issue. I am unsure if my microphone is working or not. Is there anyway to test it to see if it works at all? I am using the Electret Microphone Amplifier - MAX4466 with Adjustable Gain. I have followed all the instructions very carefully and I don't know why this isn't working. I need this project ready for halloween.

If you post photos showing all your soldering and connections to the mic and the shield we'll see if we can spot any problems.

A simple sketch with a loop() function that reads the analog input (analogRead(pin)) and prints those values to the serial port should give some indication whether the mic is working. The values should be around 512 when silent, and spread out between 0-1023 for loud noises.

Also, quite often folks forget the wire between 3.3V and AREF on the Arduino board, make sure you have that!
