How to sense sound from an insect using Arduino
Hi all
i'm doing a project based on sound recognition in matlab , i need to import the same (Matlab code) into Arduino .
Kindly suggest the hardwares and technique to complete this project

What are those 2 black forked wires with the red ends under the step?
It doesn't matter for BB view but if you PCB it always look for red ends, as it denotes a non connection.
EDIT
Also those 3 ratnests should be gone if there is a actual wire connection.

You haven't installed the MS crt runtime.
Plenty of fixes posted around here.

If I understand your question correctly... Just add the pads back into the pcb.svg. Try this one... is this what you want? PM6078-004_v2.fzpz (6.6 KB)

This multiple views thing will take some getting used to 
(I'm new to fritzing and haven't used it a lot yet), I was looking at the schematic view (which as you note was incorrect) and didn't think to check the breadboard view to see actual physical wiring. In addition with the wires physically connected as shown in the breadboard view you are correct it should work even though as old_gray noted fritzing doesn't think they are correctly connected (yet another source of confusion).
Looks pretty much like you are good to go and now its only a small matter of software

Search function in the parts view does not work
Odd as I have a couple of machines running Win7 pro 64 and fritzing 0.9.3 and the search runs fine on both. As you note on start up it is greyed out, but clicking on the search arrow causes a brief red box in the main screen (a network update check perhaps?) and then the search bar becomes lit and works as expected. Perhaps something blocking the network access (assuming it is making one)?

Yes! Thank you, that looks to be what I want, now all I have to do is figure out how you did it . Parts editor doesn't seem to be complaining about unconnected pins and the appropriate pads have re appeared. As well the fonts have been eaten as happens to me (and thus it isn't only me that it happens to). Check the breadboard view or schematic view of your file. The font size has reduced from what I think is the standard size to something unreadable which is what happens to me if I use the parts editor on the part more than once. On the first edit the fonts remain the correct size on the second edit they reduce like this. Is this a known bug or am I doing something wrong with the fonts in Inkscape somehow (I have the fritzing fonts from templates loaded on this machine and Inkscape seems semi happy with them and seems to leave them in the XML)?

I just replaced my pcb.svg file with the one from your part and all is well, the new pads show up and the fonts are the correct size. So now all I need to do is go look at the xml and see if I can figure out how to do this for future reference. Although interestingly enough, in parts editor the fonts are again too small (but since I don't intend on saving it, at this point it doesn't matter for now but I would like to find a fix before uploading the part!).
While I'm here another question: while the graphic standards suggest no silkscreen text in the part I'd like to put a label of the form PM6078-004 DC-DC Converter (and possibly +5V GND and +9V and 9V GND on the appropriate pins) as this is an odd part. Is that acceptable?

I was going to explain how to fix your pads but it was a lot easier just to fix them. It is really pretty straight forward... I will write up something for you so you know how it works...
I saw this font think once before, just don't remember what it was... I will look into that too to find out what is causing it... ... I know... "idiosyncrasies" 
Dahhhh!

Thanks, a write up would be appreciated, but it looks pretty easy. I've got the two files up in Inkscape and (other than the fact Inkscape has lost the left side and top lines on your file, fritzing seems to find it fine) it looks like I just needed to add a circle without connector ids at the appropriate grid points. If there is an easier way than manually editing the xml I'm all for it thought. Every piece of software I've ever used has idiosyncrasies but at least with open source if you care enough you can fix them and fritzing is doing an awesome job. I hope the various companies that are using fritzing for their tutorials are also providing funding (as there seem to be a lot of them ...).

Yep, that is it, just add a bunch of circles... I do it all in CorelDraw with the duplicate button... only takes a few seconds.
Wired, I didn't touch the breadboard or schematic .svg's, but when I exported the part as .fzpz it made all the fonts smaller. 
... I will fix it

I am going to try that in Inkscape and see if it will duplicate only the pad without also copying the
terminal pins. At the very worst I can use XML editor to delete only the pin parts I expect and let Inkscape do the x/y positioning for me. Yep it duplicates just the pad not the terminal pins so that is easy to do. Now on to cleaning up the metadata and trying to make a part for one of the cheap Ebay volt/amp meters that the Valor connects to. Thanks again!

We having fun yet!!! 
The schematic.svg appears to be a raw inkscape .svg, When I exported the part. FZ rewrote it into FZ format. The inkscape fonts were sized in pixels instead of points. There are also some other weird things in that file... I don't believe FZ know how to convert pixel fonts to points... all of the fonts were resized to font-size="0".
I may have to look into the inkscape thing to see what you guys are doing... or not doing...

I actually click on the node in Ink's XML Editor to select it, like the circle, then go to the drawing and right-click the boxed node - must be arrow select - and select duplicate. That way you know you have the circle and not the connector node.
I practically do no drawing in Ink. I select nodes in XML Editor and adjust size and position with the with the top toolbar. At most I do a rough drawing of the shape, shuffle it Up. Down. Indent, Unindent. in XML Editor to group it, Fill and Stroke with side box, resize with toolbar, and drag it to a custom made grid until it snaps.

Yep that one works fine. Knowing what the issue is helps a lot too. It looks like font size in pixels is a feature in Inkscape (i.e. the manual shows no way to change it to points, only how to resize it in pixels.) but knowing that I can maybe figure out how to modify the xml to set the font size in points before saving it. I'll try it and see what happens. Its a PITA but if it works I'm willing to do it . At the very worst I can use a text editor outside of Inkscape to fix up the xml. I'm coming to think that Old_Grey may be correct and editing the xml directly may be the best answer. I loaded the perl simpleXML parser on cygwin yesterday and I can get it to dump the XML (mostly, I think some of it was missing perhaps) so that may be an avenue as well. It should certainly work for checking that I haven't missed deleting something at the very least which is why I started exploring it. When I feel get a bit more competent at parts editing perhaps I'll write up a tip guide for the next poor bastard. Thanks again progress is being made!

I'm not good at direct XML coding of the .fzp file, I meant the XML Editor in Inkscape. It's simple shuffling stuff, adding nodes, renaming, etc.
In Ink File/Properties you can set global pt, maybe do that when you do fonts and switch it for other stuff.

Resistor sizes [extra text required for the title]
i guess this is beginner, so.
i have a perfboard placed out and I'm trying to do 2 things.
- extend the legs on a resistor
place a component the wrong way on a board.
i select a resistor from the core, drag it to blank space off the board, change it to THT, change the pin spacing to 500mil. no change.
tbh the ability NOT to be able to select the specific component you want BEFORE you drag it seems ridiculous to mei can place a component on a pcb, and choose the layer, but with a perfboard i am stumped. i can move the component up and down, but not the top and bottom of the board. i guess my design is too out there, as i wish the leds to be on the top of the board, but the components on the bottom.
side: yes, i am a complete beginner, as i can't even get the forum to operate as i would like... 1 = 3, 2 = 4
