Yep, it's the age old question...
well, sort of =P.

I was working on a new site, and I had an idea. A sort of 'messaging' site. When you get a message, a LED hooked up to the computer would light. Though I can program fairly well, I am not sure how to go about actually creating the LED set up.

he site is done, and so I think I can make this my new project =D. I am not sure which type of connector to use and how to set it all up (how many VOLTS are passed, which resistors to use, etc).

I was hoping someone could write me a simple diagram of how to wire it all together (some kind of connector, possibly the name) and where to stick the LED). Maybe any resources with related projects would be helpful too!

Thanks a lot, any help would be appericated =D.

Hi Omar,

There are a few ways of connecting an LED to a computer, the older method is simply connecting it to the parallel port (this is apparently harder to do when using Windows XP these days).

The more modern (and more difficult) way is to use a USB capable microcontroller to control the LED.

Of course you could use RS232 instead of USB to do the same thing, RS232 would be easier to do with cheaper hardware.

You could use this example to light up an LED using a PIC microcontroller and C#.NET http://www.piccoder.co.uk/content/view/42/26/

Nice find Bronze,

There are free samples available for this device! Very Happy

Exactly,

Nginuity hit it right on. It is for Omar Engineering and you have a new consumer prototype X that you are developing. Wink

Ditto. Although I do plan on making a business, I don't have an official one yet. Microchip, Freescale, et al really don't check to make sure the company you put in is legit.

So, which one of those would you recommend I use for this? I assume 44 pin thin quad flat packaging? Tray packing?

I have always had the luxury of not needing to specify such things Smile

Well, as long as your pins will fit, I don't see why not, unless you run a USB to serial converter, in which case, the voltage will be too low for the burn.

Sorry about the bump, but I got the microchips ordered in. So I keep checking the FEDEX tracking service, and I seem to be in a bit of a problem.

You see, the tracking information says that there is a "delivery exception" and the details state "Incorrect Address"...
I sorta made up the company =P, and it seems that FedEx was looking for a company at my address (they probably found a big apartment building)

So, any ideas on what to do?


Did you not use a unit number as your apartment number?

There is certainly nothing wrong with having a company go to an apartment address. In fact, I have a valid LLC on the books at an apartment address.
