Review on DFROBOT Gravity: 1602 LCD Keypad Shield For Arduino - Simplify Your Arduino Projects with LCD Display and Keypad Interface by Russell Rabbach

My review should be preceded by the fact that I'm very new to Arduino and this may have some impact on the outcome for me, bye! After installing additional libraries, I was able to get the demo program to scroll 0-9 across the top line of the screen, then to the bottom line and repeat it. After playing around with it (sketch) I was able to change the program to show the message, but not very well. I couldn't sync the top and bottom rows or get them to scroll. The documentation for these modules is crap at best and just needs a gimmick to learn how to get it working. The example provided doesn't even attempt to explain the code and assumes that's all there is to know. Again, I'm a beginner, maybe after a few years of programming I won't find it that difficult anymore. A strong YouTube account is required to better understand products that can be launched quickly.
