Can Me Sound Sensor be used to detect frequency with custom code?

#1

Is there any way to write custom code to use the Me Sound Sensor in the Inventor Electronic Kit to detect frequency of sound? I’d like to make a program that can make decisions based on frequency/pitch like piano keys to change direction etc.

Where is the code located for the MeSoundSensor object? Would it be possible to modify any of this to use frequency detection code to analyze the signal (with other rj25 pins perhaps)?

@mcassisa,

I looked into this about a year ago. I would suggest Googling “fast fourier transform arduino” and look through the results. You will need to use the Arduino IDE to do the programming.

I hope this points you in the right direction.
