Huh, fascinating! Are the trimmers that much bigger than resistors? And when selecting one, does the Wattage/Voltage values matter for what I am doing?
They are not to large. I think 5 or 6mm square is easy. The mechanics makes them larger.
And I have made the adjustments to my diagram... I assume then that when something connects to the middle of the "trimmer" in your picture implies that the middle leg of the actual trimmer is the one connecting to each element.
Right you are the center pin will be the one with the arrow in the diagram.

So from your diagram it sounds like once I have it all wired up like this, I just need to attach the battery when it is full, and adjust the signal trimmer til all the LEDs light up...but what do I do to adjust it for the low-end trimmer? Wouldn't that one's "wiper" already have to have been set?
If you have a voltmeter you can use it to set the bottom one to .88 volts. Do you have a voltmeter?
The way it is set up now only one led will light at a time. It is called dot mode. You can change it to bar mode but keep in mind all the power for the leds comes from your battery so it will go dead sooner if you leave it on.
