There is a P-Channel Mosfet in the inspector list
Do a search in the search bin.
Thanks but where do I find the search Bin?
The magnifying glass icon in the parts bin on the right hand side of the Fritzing window. You need to search for mosfet (as there isn’t a irf540 directly) and that will turn up a bunch of choices in various cases. You likely want the Basic Fet N-Channel which is a TO220 footprint (which should be correct for an IRF540 I think unless yours is surface mount).
Yeah, just grab a basic FET and just punch the number into the Inspector to give it your part#.
