Looking for help with some coding issues I'm having. I'm fairly new to this but my project isn't the most complicated. I'm using a circuit playground express as my controller, circuit python for coding, a KY-040 encoder, and a 1156 LED bulb with a BA15S base. Here's what I'm trying to do:

I have a modular mechanical sculpture with linear functions that I'm trying to translate into variations in LED intensity. This happens in 44 different places across the sculpture and so I will have 44 identical setups of the hardware I listed above. In each setup the limits of the linear function will be different, moving as short as 3 inches and as long as 9 inches. I already have the encoder mounted appropriately and have been able to read the digital output on my serial feed.

What I'm now trying to do is two things. 1: take the encoder output data and translate it into led intensity, going from 0 to 100% brightness. And 2: program the A and B buttons to identify and set the limits of what is 0 and 100%. I.E. Once I have the mechanics assembled I want to be able to move the linear function to the lowest limit, press button A to reset the encoder position to 0 = zero light output. Then adjust to the highest limit and press button B to set whatever position the encoder is at to the maximum light output. The button functionality will allow the mechanics to be completely modular and not require unique code limits for each of the 44 iterations.

I don't have the bulbs attached yet so I would like to have the digital output be the variable for an on board LED in the meantime. Can anyone please assist with my coding? I have watched multiple videos about programming the buttons and none of them have seemed to work for me.
