LCD display +arduino 1 using makeblock 5


Hi there. I am using extension JSV LCD V1 extension in MBlock5 to conect an 16x1 LCD display to Arduino uno.
I have checked the connection pin and the wires, the screen is on but no text is displayed. I don’t know if the problem is that I have to download any kind of library to the computer in addition to install the extension directly in mblock. However, I’ve checked Mblock folder and inside ext/Arduino uno I can see no library.
This is a screenshot of the program I’m trying; even it is in Spanish I suppose it is clear enough for you.
Thanks for your support


Pls double check if your cable connection for Uno pins is right or not,for details you can check on this link.
