RC CAR (Parallel port interfacing)

INTRODUCTION (WARNING CODE CAN ONLY RUN WITH WINDOWS XP)
This project was about operating a remote control car by using an input device connected with a computer, for this purpose we had to connect the remote of RC Car with the computer so that when we operate the computer, remote would start its function and car will be operated. Therefore at the same time we had two grounds to play one was software development and second was hardware interfacing.

Nice to see a project that does not use an arduino. There are a boat load of old pc motherboards around that can be adapted easily for this type of project. Also goes for recycling old equipment. I have done several instructables on this sort of thing and wish people would do more. I intend to do a mod on a 486 laptop to do the same thing, but boot with a freedos floppy and use a compiled freebasic program. Have not made time to do it yet.

thanks for visiting and if u have any problem u can ask

Thanx for the offer, but I can probably handle it.

Dude, I can't find the transistor at a local electronics parts shop in Islamabad. They tell me MPSA06 is American part number and they have Japanese/Chinese parts. They say the part number has to be 2N-something or like 7806C or 7906C. I'll check College Road after a few days; but, meanwhile, I am trying to find an equivalent of the transistor you used. Any help would be welcomed.

dear
u can find it on college road at "IC Master" u can use any transistor that is feasible for switching purpose or even u can use a generic transistor .....

still if u r confused try
www.alltransistor.com
or try this
http://alltransistors.com/crsearch.php?mat=Si&struct=npn&pc=0.625&ucb=80V&uce=80V&ueb=4V&ic=0.5&tj=150%C2%B0C&ft=100MHz&cc=-&hfe=50MIN&mnf=&caps=
for equivalent transistor or use C828 ......

thanks for ur comment .....
u can still ask if somethink is nt clear

Hey Nice Project really easy to do.
But what if i wanna do this with usb and not serial port ??

[usbg3rd]

yup u can but u have to change the coding likely .....
its more convenient that u use a usb to parallel port converter it will b easy else the whole code will b changed

[n33r]

Alrite m gonna give it a try.
Thanks for help!!!

[usbg3rd]

no problm
actually in parallel port one can handle each bit saperatly while usb i think transmits searially
