I have a working project where I am using an ULN2003 darlington array to power an RGB LED strip.
I want to expand to a bigger strip and have therefore bought some MOSFETs from sparkfun as these could be controlled directly from a microcontroller...
I have seen a few projects with MOSFETs, and some use transistors to drive the gate. Some use pull-up resistors and some use resistors to protect the mosfet. Now I'm not sure what I need. I thought this was just replace the darlington with the MOSFET :(
Looking for some advice :) How to wire it all up. I have 12v supply voltage and 5v from the arduino board, also using the PWM outputs on arduino.
