so plzzzz can any one help me too ,im also working on the same project, i need a full circuit diagram so that i can connect my parallel port with rc car, and one more ques , what precaution should i take to save my parallel port from gettin damaged if there is abdrupt increse in sink current.

But instead of connecting the motors connect the remote ( shorting point of joystick on RC ) to the relays . And u have it done :) ..... not even a 1 hour job.

friends, can i use L293D to drive my both motors of rc car simultaneoulsy ..coz i just went through an article in which they r using L293D..i guess it will be more easy but i still dont know whether it can drive both motors simultaneously or not. One more ques. if im using L293D will it be enough to save my parallel port or do i have to use zener diodes or something to stop back emf...plzz help me and plzz post as many link u know about controlling RC car's DC motor...neways thanks for that link,vikas. YESSSSS one more thing the supply which we r giving to L293D i.e VDD is that for motors .....plzzzz help this little kid :( :cry:
