This project started out as an idea I had to allow my robot to “hear” sounds in it’s environment, and to add new behaviors based on this device. I started out by looking on the web for microphone circuits which then led me to another site that explained how to power microphones. This was my first section of my circuit design. My next step was to find out how to utilize the output of this simple mic circuit, which led me to the Parallax forums. Bean was kind enough to get the ball rolling by presenting the use of an op amp to increase the gain of my mic. This got me to the second stage of my circuit design. Now I had a powered mic feeding into an op amp to amplify the mic’s output. I still needed a way to compare left and right audio and to have the output usable for the basic stamp. This brought me to the third and final section of my circuit design. With a lot of help from Beau Schwabe, I was able to get starting values for the design and was pointed to resources that describe the use of AD converters.
