Thanks CJ and GRJ. Creating my own component parts sounds like an advanced feature that I'm not yet ready to take on. But it's nice to know that it can be done.
I did manage to download and install an Arduino component library and that part of this exercise is moving along.
I think finding the right parts is going to be a continuing challenge that I'll have to get used to. I may have to delve into the component editor sooner than I thought. Meanwhile the internet search capabilities are a modern miracle that can be put to good use.
