    Hi, I'm doing a project where i have a 13A dc power source. I need to split this current so that 9A go and run a motor and 4A i need it to send to other system. Can anyone help me how to do this with a microcontroller or if possible through some other means?? and will i need current sensors or do i get them in microcontroller?? I'm running out of time for this one. So please try to reply asap!!

    Have you tried some wire?

    As long as the motor draws no more then 13 A and the "other thing" draws more then 4A there is no need for a micro or anything else. The current will go there it needs to go.

    Pick the most important one eg. the other system can't drop below 4a. Then use your sensor and your MC to ensure that.
    Current sensing is harder than voltage drop sensing.
