MSGEQ7 Arduino Library

The digital section of my Bright Light Controller is fully functional and I’ve gone ahead and made a library to help interface with the MSGEQ7 IC.  As of Version 0.1 the library will probably only function on a 16MHz or slower Arduino.  This shouldn’t be too difficult to modify, but I haven’t gotten around to it yet.  A video demonstration of the library performing a “readAll” is provided below.

Orcad Capture: Use a Custom Symbol

I ran into some difficulty when trying to use my custom Mosfet symbol in a Orcad Capture Schematic.  Everything went well up until I attempted to run a simulation where I ran into a Subcircuit undefined error.  Unfortunately there isn’t much about this whole process that’s been intuitive.  Here’s a simple patch to get the model to work.
