Project Scope

Technical Specifications

  • The Arduino can hear sound through the microphone
  • The Arduino calculates and temporarily stores the frequency of a sound
  • Information associated with each frequency can be assigned in code
  • Serial Monitor outputs the associated information for a frequency

 

Code

(These can be found on the Research page.)

The code in HueHarmony2.ino is the current code used in the device. It incorporates code from Instructables projects, and from the Audio Hacker library.

The code in Sampler_12bit.ino is how we know that the microphone is listening for sound.

 

Circuitry

This is how the Spy Listener microphone is connected to the Audio Hacker.

Circuitry (Alt)

This is how the electret condenser microphone is wired to the Audio Hacker.
