Just looking at the Ikea didoer LED lighting circuit (an RGB lighting scheme)...
if you look at the associated schematic, you'll see that between the PIC PWM pin and the MOSFET gate, there is a 150R resistor....any idea what the resistor is for?

the datasheet shows a gate similar resistor...

Many thanks.
