Make components Picaxe VSM

Hello

I want a photodiode or transistor, neither of which are in the component library.
I decided modify the LDR component, but couldn't figure out how to do it.

I want to change the shape to transistor or diode and modify the sim values, still keeping LUX IN.

The tutorial doesn't seem to cover making your own components very well.

Has anyone tried to do this and if so, could anyone direct me to a tutorial.

Cheers

Mike

Making your own models is very involved and needs a good knowledge of how SPICE models operate, and you certainly can't make a phototransistor out of an LDR (a normal transistor would be a better place to start).

The Labcenter help documentation is the best place to start reading if you want to learn how to make your own new model.

Technical, I was attempting to modify an existing model as an exercise in so doing, not because I believe an LDR functions like a phototransistor.
