I successfully built a project using 7 segment LED display, it works perfect! Very happy with the function of the code with LED display - the only problem is it's not viewable outside where I plan on using it most of the time so after a ton of research it appears LCD 7 segment might be a good option, similar projects use this type of LCD display (if you have a better idea, I'd like to hear it and why it'd work well)
This project only needs to display numbers and the numbers are updated every 1 second. I think the static LCD will be perfect and it's clearly viewable even in direct sunlight, I only need 3 segments and the LCD's I currently have are Lumex 3 segment. My goal is to have nice large 3 digit numbers clearly displayed that can be read outside, the numbers will update in the code with millis() every second.
The issue I'm having transferring over my design to use a reflective static LCD - I can't seem to find any information more than an explanation on the theory of how to correctly drive an LCD since it requires reversing polarity (AC) I have some ideas on how it might work and I've seen a proof of concept using XOR for one pin, driving the com pin and flipping the other pin with an XOR, the explanation I found basically ended there and left me with no practical idea where to start, I'm looking everywhere and can't find anything on driving a static LCD with arduino so I'd appreciate any help pointing me in the right direction, I am completely stuck right now and would appreciate any help.
I would like to drive the LCD correctly so that it lasts a while or if there's a better option I'd like to know what that is.
Thank you everyone one on here!
