Experimenting with Sound Localization and Arduino

Today I'm going to walk you through my experience trying to localize the source of a sound using Arduino. My goal with this was to add a feature to my robot that would make it more interactive and look more "alive". Beta 1 What you normally see people doing, as an easy approach, is to measure the volume level from two microphones in which the amplified output is connected to the Arduino analog inputs. Whichever input is higher determines the source direction of the sound. On the practical side this proves to be…continue reading →
