Shift Mosfet and H-Bridge for Arduino Question? Answered

Hi guys, Im Rinozen.. Im newbie on Arduino and Electronic ^_^

Anyway, can you guys please help me? Look at the schematics i've uploaded. Are there something wrong about the track? And what value for the Resistors and Capacitors for the right choice?

Sorry about my english ^_^

Thanks for reply... :)

If you use MOSFETS, you don't need the resistors. You DO need logic level mosfets, but you haven't said how much current you want to handle.

...OR you use a ULN2803 chip, which, if you currents are less than 1A, and the voltage is less than 36 can be had for less than a dollar.

The '595 will keep the gate either high or low as needed. Put a 100K pull DOWN resistor from the Gate to ground.
