    hi! everyone

    Though this is simple question, i just didn't wanted to make any mistakes so..

    If i want to turn a relay is it better to use ULNs or TIPs?
    I am confused cause i know both are so good drivers. If i use TIP then will i have to connect a pre-amp-type transistor?[<like bc547?> I want it to turn on with logic level "0"]
    PLEASE HELP..THIS DRIVER IS FOR MY ROBOT WHEEL..btw i also tried L298 but it didnt work for me!! argh!! plz if any one of u have idea of good relay driver or directly "MOTOR DRIVER" then please post or email me.
