I did a search for a breadboard power module : Beginner looking for breadboard power but when I download that Fritzing part all is shows is a breadboard and not the actual board. Mine is an Elegoo power supply module with 5v and 3.3v options on either side. Help to find the part would be most welcome.
as you can see I expected to see the power module albeit a different brand but got a breadboard instead.
I am new to this so please forgive any errors on protocol
regards in advance
While without a web site of what you want, it is hard to say, but it appears you are looking for this
which can be found via a google search of the form “fritzing part breadboard power supply”

I have done the best I can but not sure how to get a simulation working, Help would be appreciated as I think I am almost there.

You have a variety of problems, some fixable, some not immediately. First your layout is wrong (which is fixable):
Here I clicked on the green arrow in the lower right of the image. That lights all connections in the net yellow which indicates a short between power and ground (and that the groups in the power supply part are not correct but that won’t matter here.)
in schematic if I drag the wire circled in red left we see the short (which will reflect in to both breadboard and pcb!)
so in breadboard I left clicked on one pin of the fsr (green arrow) which tells me this is pin0.
then in pcb I did the same to find pin0, as we see from the rats nest line that connects R1 to ground, that should not connect to the FSR but rather like this
it should connect like this
with that corrected the short in breadboard disappears.
these changes to make the layout correct are in this sketch.

However this still won’t simulate because a number of the parts don’t have spice information and without it simulation won’t work. The fsr does not have spice information (it is basically a pot so it could be added and may have been in the simulation parts.)
same with the power supply. There is a power supply that can be simulated but it doesn’t look like the Ywrobot (it is a bench power supply.)
same for the lm358
there may or may not be a part for the lm358 with a spice model in it. I think there may be a bin with simulation parts in it @fai (who wrote the simulator) can probably give you better advise on what is available than I can.

@vanepp is right. You must use parts with spice models.
FSR: You must replace it by a resistor or potentiometer to be able to simulate it. Also notice that you are using an obsolete FSR. There is a better part with a better symbol in the sch. To use it, simply replace it with the one in the CORE bin.
The power supply needs to be change to a battery to be able to simulate it.
LM358: You must find a spice model from one of the manufacturers (e.g., https://www.st.com/en/amplifiers-and-comparators/lm358.html#cad-resources ) and add it to the part. This can be a bit tricky and it is not super straightforward.
And you my find some hiccups (need to change to PSPICE compatibility or load other libraries). See a similar issue here: OPAMP OP37 Error when loading the netlist · Issue #4185 · fritzing/fritzing-app · GitHub
So, Fritzing has the functionality to do it, but we are still working to integrate more models and make it easy to simulate more parts. Currently, we are trying to integrate some AD parts with spice models that will work off the shelf, but it may not be easy for non developers.
these pictures are very helpful, thank you Peter.
There is a big learning curve but your links are a great help to get me started.
