Robot Sound Sensor Demo

The custom robot sound sensor connected to the Basic Atom Pro. Testing the circuit interface. My parrot interrupted with a chirp causing the head to move before my hand clap at the end, then, windows movie maker locked up for a second when I started to snap my fingers.

Anyway, this video demonstrates how you can cause the microcontroller to do something in response to the sound detection; in this case, it is driving a head servo.

nice, but next time try it on different spots, looks like you just used sound recognition and make the head turn to 1 spot and back instead of looking where the sound is coming from

You are correct; it's just a trigger that moves the servo in only one direction. Perhaps it's possible to build two sound sensors and then calculate the time variance between the two triggers to get an angle. Math is not my strong point. My goal was to have my robot react to sound and this simple audio sensor was the best my noggin could come up with :)

hello:D...could you send me please the circuit schematic of the sound sensor?my e-mail address is kool_dude957@yahoo.com

@lupdan777 I already sent you the Schematic yesterday.

@Botwire still, nicely done. I guess it's kinda hard to calculate the angle but thats what we're programmers for right? solving problems ;D
