I am making a special indicator for a lathe threading application. I like the LCD "graphics" display you created so much that I am stealing the design. I will put an attribution in the code of course.

Hi, This is a good project, inspired me to use your project work as a one baseline feature for my project. I put attribution in my project. Thank you and have a great project as always. Cheers
