Hello,
I'm looking for the LM3914 calculator. Unfortunately the link no longer works. Who still has the tool and can make it available for download.

Thanks and greetings
Daniel

Hi Dana, thanks for the help, unfortunately I can't get any further with it. I have no idea what to do with this web application from github. I don't have a suitable device for the Android app and the link doesn't have a download button for the calculator. sorry maybe i'm being too stupid. Nonetheless, thanks for the effort.

Why not just read the datasheet, and work it out on a piece of paper - it's only two resistors, and a very simple formula.

It would probably have been just as quick as typing your original post?.

Unfortunately, no. I have no idea about this, I'm not an electronics engineer and I don't understand a few things in the datasheet. A few months ago the pocket calculator worked here. (https://www.electro-tech-online.com/blog-entries/single-and-dual-lm3914-v3-0-calculator.136/?page=1)
It was easy to see how resistance and voltages interact with each other. Well somehow I get my project to run.

All the calculator does is put your entry values in, and run the formula - it's basic maths, not really electronics.
