    hi every body ... i need some help in how to design an tip41/tip42 h bridge and interface it with arduino
    also is this type of transistor is suitable to drive a 24V/4.5A motor...

    Not likely. The TIP41 only has a guaranteed gain of 15 at that current and an Arduino can't supply 300 milliamps.

    Any further discussion requires that you post a schematic of your circuit.
    Go advanced, manage attachments, browse, click, open, upload

    thanks for your response, and i will always respect any opinion....
    but what if i use other low base current transistor as interface ,,can any one give me the number of transistor can do this as interface between tip.xx and arduino..
    and finally sorry my English is not good i know that

    Use a 2n2222 or bc337 for NPN. 800 mA. You can also hut replace with on piece darlington transistor.
