Can I use my laptop instead of a microcontroller?

I have a lamp. Her three LEDs - red, green and blue, respectively. I want to make some kind of Pribluda out of this, but I have no microcontroller. Can I use my laptop instead of a microcontroller?

If he has a GPIO that does not see obstacles.
If not at least buy TTL whistle. But this is more costly than Arduino or 85sparkfun

If your laptop is old, has an on Board printer port LPT, and the number of managed devices exceeds 8, then the answer is Yes. The fact that the LPT port is easy to manage the software, and any knowledge of information exchange protocols will be required. You just have to write the ones and zeros in certain registers of the port (at fixed addresses that are configured in the BIOS), and eight lines of the port will appear signals with levels +5 and 0 volts. And how to use these signals, shown in this picture:

in nature exist at all, the laptop with LPT?) - chase14 commented on April 4th 20 at 00:36
@chase14, about 15 years ago and only those existed.

@Brock, the probability that the author of this not 0,001% )) - chase14 commented on April 4th 20 at 00:42
@chase14, while the author of the question is neither confirmed nor denied, we may long to shake the air and Claudia their computers. But even if he confirms that his laptop has no LPT, then he has the opportunity to go through hamovniky relatives and friends, and to find the right device (and I put "marked solution").
Well, if not - no court, no. - Brock commented on April 4th 20 at 00:45
@chase14, Maybe he has a military dad or the mechanic?
There LPT is still in demand. - Johanna.Hanse commented on April 4th 20 at 00:48
@Johanna.Hanse, none of nynezhivuschih people don't use a laptop with LPT - chase14 commented on April 4th 20 at 00:51

Some of the famous characters said "Never say never". I would add that "no" is also not necessary to mention in vain, and it is possible dull to fly. - Brock commented on April 4th 20 at 00:57
@Brock, 0,000001% of the total number who use laptops don't count. Extras ignore such figures. - chase14 commented on April 4th 20 at 01:00
