-* Generating strobe and reading the ADC values need precise timing. One missed reading will messed up the data representation of the frequency values.
+* Generating strobe and reading the ADC values need precise timing. One missed reading will mess up the data representation of the frequency values.
 ** Using digital analyzer greatly helped the team debug the timing issues.
 * The <b>MSGEQ7</b> chip is very sensitive to noise. In reality, this chip wouldn't perfectly filter-out the surrounding frequencies; thus we should look only to whether or not the target frequency has the highest output voltage.
 ** Using online frequency generators, together with the logic analyzer, helped the team debug the system.

 In addition to testing the LEDs for functionality, tried to figure out the maximum current needed to power the LEDs to ensure we would be able to supply enough current.
 This was done doing the following:

+In this section we provide an overview of our design methodology for the equalizer and LED matrix individually and then we look at the integration of the two.
