As it stands now, my dosing pump project works perfectly, and the functionality is just right “all” thanks to Blynk! However, if this project is copied by someone with even less code/circuit skills than myself, I would want them to have an easier to understand project in the end.
THIS youtube video depicts the functionality of my project while also showing my app being interacted with. I refer specifically to the first Step widget titled PUMP#. This widget allows me to select from 1 of 8 pumps. I as the creator will know what I put on pump 1, 2, 3 etc in terms of nutrient solutions, but other users, especially those that use this as a bartender would likely be consuming the cocktails made and likely forget which liquor is assigned to pump 1, 2, 3 etc. All of that said, and as the title states, I would like expanded functionality of the Step widget to include a variable name display, or even a new display app that can piggy back onto existing widgets to display the names in the array. As of this morning, I updated my sketch to print these names out onto the terminal monitor when the code is being executed on a respective pin and array position, but this is an ‘after the fact’ result. I seek the ability to step from name to name instead of number to number.

I will do my diligence and read and reread and rereread till I comprehend them. I do find it somewhat easier to learn a new coding skill when it directly relates to my project. Just gotta get over this hump!
so this is mostly a hobby. Don’t expect miracles 
I share what I understand
