Hi all,
i have a project that switches on a variety of LEDs for a scientific instrument. Three are UV, IR and White and the remaining three are packaged in an RGB led with a common cathode. The problem I now have is that as seen in the circuit attached, my MOSFETS are wired (and soldered...) in such a drive that the LEDs have a common anode.
My question is this: what do I have to do to make this circuit operational? I have heard that one can do this with PNP transistors?
Thanks
