LOL Yeah, Im sure phrases like “I dont think that will be all that difficult” have to rank right up there with “Hold my beer, and watch this…” I have been kicked in the butt many times after saying, or thinking, that exact thing. 
I know you mean well, and I thank you for the tips, but… Im sure those would be a great start for you or anyone who understands the programming - even a little. For me, you may as well ask me to jump over the moon before fixing breakfast.
At the moment, just thinking of doing that makes me want to take a nap and then pop some pills and take another nap.
I would like to think that I could do that stuff - eventually, but thats just not realistic any more. I just dont have the mental energy or time to put into learning the language well enough to be successful. It would take a dedicated effort over a long time period and Im just not up to that any more. I could do some stuff - if someone holds my hand. I could change variables or pre-set values to modify how program functions - IF - some told me exactly where they were and what to change. Im pretty sure I can figure out how to load a program onto an Arduino - with some review and trial and error, and I know I can assemble the various parts, provide power, and other simple stuff. But not the programing.
LOL I love you two going on about ‘agile/modular’ systems, and how the ‘new guys’ suck. Us old farts need to stick together!!
