Build an H-Bridge Motor Driver with 4 N-Channel MOSFET


I have bought 4 N-Channel MOSFETs to build an H-Bridge Motor Driver. My Motor drive and my power supply voltage is 12v. My TTL logic voltage is 5v as I want to speed up/down the motor with uC PWM. Now I have understood that I have problem with driving High Side MOSFETs as their Gate Voltage must be bigger in respect to their Source voltage. What are my options now? shall I change them to P-Channel MOSFETs?
