Attached are two tools for breadboarding,the first by Ray Wilson and the second by westhaus of the PICAXE forum. Westaust has made great improvements like component physical size and offset wire options.
Trying again,cannot get the url,s to attach,so typing them.The first one will take you straight to the breadboard program.The second one you need to go into the picaxe forum and look for PEBBLE
Could a excel spread sheet do the math for curcuit ,
that would be great to drag a part and see the math as you build

really be a keeper.
