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

First of all my review should be based on the fact that I am very new to Arduino and this may have some impact on the score for me, bye! After installing additional libraries, I was able to have the demo program scroll 0-9 across the top line of the screen, then to the bottom line and repeat. 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 shit at best and just needs cheat to learn how to get it working. The example presented doesn't even attempt to explain the code and assumes that it represents everything you need to know. Again I'm a beginner so maybe after a few years of programming I won't have such a hard time. A strong YouTube account is required to better understand products that can be launched quickly.
