Ants are insects and are remarkably difficult to hack: they are very small, so hitting them with an axe is difficult, and they do not have internet access so virus code injection is next to impossible.
If you get an email telling you that you can catch Swine Flu from tinned pork then just delete it. It's Spam.
but the problem is i need to extract the template from the fingerprint each time i need to identify someone
and that takes 45 second depend on the database for me this to slow
my problem is with passing the database values
This shows that you don't know what WiFi really is. It's a wireless Ethernet interface. It's a carrier or transmitter and receiver of other transport protocols, not an implementation of one. You cannot transmit a file using WiFi.
You have to use an application protocol, like FTP, HTTP, or even a protocol of your own design, transported via another protocol, like TCP/IP, to communicate with another device or computer. Look at what TCP/IP stands for: Transmission Control Protocol/Internet Protocol. It's a transport protocol, not an application protocol.
yes...it will...though I have been doing some research and I think a DB25 serial connector will be easier to work with if I use an IC with Darlington pair arrays to interface the PC port and the LEDs.
I now need references.
any help will be highly appreciated.
For how to send commands though a serial inteface I only can refer to one of my article[^]s becausee I have not much expeience with hardware programming. Maybe the manual of the DB25 connector gives you some information.
If you want other opinions you may should ask about experiences with the DB25 connector and the IC you want to use in the Hardware & Device forum[^].
Considering todays machines are not even coming with serial and parallel ports, you're entire premise of using them is already dead in the water and limited in scope to the lifttime of the hardware that you are currently using.
Since you already know a bit of eletronics, just go with a microcontroller that can run the .NET Micro Framework and be done with it!
Oh! and those can already be programmed over USB using Visual Studio 2008 and up, if not VS2010 and up.
By writing appropriate code for what you want to do.
What did you think the answer was going to be with a question like that??
In all seriousness, if you want to use C#, get a Netduino[^] or a FEZ Panda[^] microcontroller and learn how it's really done, without risking your computers expensive hardware. You'll also learn alot about digital electronics if you really want to teach yourself. Try getting this book[^] or this one[^].
it depends on what you need , if you have a Com ports you can use it easily with some hardware buffer and amplifier , or you can use any controllers, if you are not familiar with Arduino or PI , try to find a CanaKit board, its very easy and with LED's and Relayed output.
