Thank you all for your inputs. Much appreciated. I will read/watch and digest.
Rod, the current software does use the serial interface as I had to assume the display was not working and since the software would have been uploaded that means the USB post is working. So I use the same setting for the serial monitor built in the IDE. I like the idea of the LCD pins cycling as I was wondering what could be done to test the LCD at a lower level than sending characters via the library.
Jerry, looking forward to you new software.
Bill, yes just a few components and some simple software. Smart and inexpensive.
Jack, I need to view the whole video. Thanks.
