Ok I know to a lot of you this will seem dumb but im soooo excited about it so don't kill my happiness :angry: ! Anyway it is very simple and I got the code and idea from here http://www.josepino.com/pic_projects/index.php?led_chaser.jpc This PIC came with my programmer and I figured I'd put it to use when I found this cool code. I just installed a jewel in my pc and flashed PIC and wired to unused jumper cable in PC witch had 5v on it so i just removed all components but the IC and replaced the 1k ohm resistor with a 100 ohm and wired leds according to diagram and wraped them on the inside of PC behind jewel so the leds flash in a circle around the jewel and viola! IDK why but those lil leds flashing in a circle just amazes me I finally have a pic programmer!

Ya I look at it, and I just see so much potential too bad IDK the first thing about programming :confused: but ill get a video of this thing in action in a few days im leaving to orlando for the weekend to help my grandparents in a few hours

Sure. But to fade it you will need a digital pot. You might be able to blink it in a manner that appears to fade,

Hey all right! That is a very nice project, wish'd the source code was posted but overall it is a simple code to make.  The technique of being able to operate 2 LEDs from 2 pins is called "Charlie Plexing", there is a ton of stuff online for that.

Essentially you are making all your outputs digital and on the pair of pins you are using for your leds, making the first side 0 and the other side 1 you light up one of the leds.  By reversing you pins logic by making the first side 1 and other side 0 it will light up the other led.  I works well with very few components cuz the pic can only source 25mA per pin so there is no need to limit your leds(hazer: I know we have argued this before but the proof is in the pudding).

The code is a simple loop that will toggle the correct pins with delays in the middle, easy peasy, it would be a great place start with programming micros. 

EDIT:just saw this in my travels, check out tip#2. it uses a similar configuration to the one above, but is different and will make for different effects.

Also to make it slower is going to be very difficult with just a .hex code that is provided, however making the LEDs fade may be possible with an RC Snubber circuit, but will require at least a capacitor for every pin.
