  • Updated Example Code

    The VU meter used in this tutorial has been updated. The preValue is initialized at the top as a global variable since we want to compare the previous VU value. Otherwise, the previous value will constantly be set to "0" when the VUMeter() function is called. As a result of the value being "0", the while loop after // Only print the volume unit value if it changes from previous value does nothing.

    Sonic Control Using Filters

    For sensing certain frequencies, you could use the MEMS microphone with a filter circuit. Here's a good tutorial on filtering out a certain frequency with a bandpass filter => http://www.instructables.com/id/Sonic-Control/?ALLSTEPS.

    I'm trying to use this microphone to create dancing leds. For this I am using a Tiva C microcontroller, but I am not sure if I have to add additional libraries since the code is not the same as it would be for an arduino
