i have search the forums and notice that some others have made their own using an op amp and ad converter. But i was wondering does anyone sell premade sound sensors for robot use? something what would send pwm to a stamp of the db value.
Hitec has a sound sensor that provides a high output that goes low when a souns is detected. I have not used it, and I do not know how much “processing” is done on the sensor.

It’s plug and play with the Bot Board.
