This is a project I have been working on for quite some time now (about 2 years to be exact). And I have FINALLY.... Well... ALMOST have it completed, however I am finally ready to post the source and schematic for it (beta still btw). Hope you like!
I used the Arduino IDE to compile this code, and just pushed it via avrdude through icsp, so just to give a heads up I don't think this will work in avrstudio (well without a few adjustments anyways).
Source Code:
****BE WARNED! THIS IS BETA STILL! I CAN'T GUARANTEE IT IS STABLE AND THAT IT ALL WORKS!!!****

//Global variables and reassignment of pins
Will show more as I get it up here.
Also there will be a youtube post with it in action soon.

| Exit sign poining to the bloggest with the bestest erm... best something :P |
 |
| Another pic of the exit sign in action |
 |
| Reflective material behind exit sign with leds (i.e. yep you guessed it, aluminum foil) |
 |
| Full underface of exitsign |
 |
| The back |
 |
| I wanted the batteries to be housed inside it but wanted easy access to them without disturbing the inner parts. Also of note, on the left we have the Microphone jack (because the whole original purpose was for it to light to music which it does :) and on the right we have the mode selection non-functioning switch (do NOT buy these crap radio shack buttons! I found out the hard way :/) |
 |
| Ah yes, the inner rats nest and pcbs that are the brains of the operation. |
 |
| This is pretty much just your standard arduino-esque board with an Atmega328p, and a really rough looking ICSP port minus the VCC pin. |
 |
| Here is where the magic happens ;) This is (though you cant see it from the cap on top) is an lm368 audio amplifier/generic opamp I got at radioshack that converts the analog audio from the microphone jack to power waves to be read by the analog 01 port from the atmega to then convert to digital to process and display the sound on the board. |
 |
| Back where the mic jack and that crappy switch is. |
 |
| Sensitivity pot for the amplifier. Works like a charm too. |
Here's pretty much the closest thing to a good schematic I have atm:

Will show more as I get it up here.
Thanks for sharing this im going to make 1 i try this if it works and will be back if its working great.
