  • Hi Byron, thanks for these detailed instructions! I am just getting back to the project now, I’ll be following along and let you know if I have any questions. Thanks again!

  • I have this connected to analog input of a spark core (similar to arduino) and I am trying to figure out a formula to measure decibels. The formula I’m using must be incorrect because I am not getting readings that correspond with decibel ranges. Can you tell me how you are measuring decibels with your sound detector? FYI, here’s the formula I’m using:

    (20 * ( log ( voltage1 / voltage 2) ) ) – voltage 2 is a constant, voltage 1 is the analog read. Thanks!

No public wish lists :(
