Another N channel enhancement mode MOSFET driven directly by a PIC12F629

So, yes, a low resistor in the order of 10-100 ohms max. is what you need. Or even better no resistor. Mosfets have insulated gate and no current flows through the gate (besides the spike to charge gate capacitance).

Hi, Ioannis

Without a series resistor, you could have some surprises ( the RMW well known "feature" ) ... try i.e. an IRFZ44 or IRL2203 - or some nF+ range gate capacitance device - ...

tested ( and debugged ) !
