The dupont pin headers single row is easier to make I would assume and it would be more useful...

the DUAL ROW option doesn't work on a breadboard if it has more than 10 pins... In order to have a 20 pin DUAL shrouded on a breadboard the base would have to be wide enough to span the middle of the breadboard... yet in the pcb view have a normal DUAL footprint....
Well this is my guess...
When I tried to change a 10 pin dual to a 10 pin single row... the image
wasn't reflected in the breadboard view or I did something wrong. LOL
===========================
Thanks for considering adding a readme.txt file in your next version...
To bad you just couldn't copy my text and create a readme.txt and then
re-zip the current version to include a text file of install instructions.
Secondly, there are free windows installer programs that will create
a windows installer that will prompt the user to include installing
external applications such as the C++ files. I hope, that you will consider such a tool.
Years ago I used the installer shield... it was easy...
Thanks Peter, it looks like I just have to look around a bit more to find what I needed.
As for the external battery it would be nice if it was rotated 90 degrees so that it can be placed off of the bread board (giving access to the whole bread board.
And the red and black wires to extend in such a way that the rotated batteries would have a longer wire so that it would be easy to attach the batteries to the
neg and positive rails of the bread board.
I am a LAZY programmer ... if it was me.... in the breadboard window
I would just LIGHT UP or highlight all the POS and NEGATIVE rails on the breadboard... no image of batteries.... but have a image of the battery supply in the Schematic and PCB view... just so it is there.
I really wish I was younger and remembered my programming this would have been something that I would have loved to be a part of. I know how much work you have done... and appreciate it. It is very impressive... to say the least.
