    is it possible for microcontroller pwm to drive mosfet however the mosfet needs 10 v to turn on while the output of the micro don't exceed 5 v

    There are 5v gate level Mosfets, for the simple low power switching such as relays etc, there is the 2N7000 FET darlington-equivalent designed for this purpose.

    MOSFET is a voltage controlled device, depending on the characteristic, at 5V, the mosfet could be saturated at lower drain current. Datasheet would be helpful.
