iam very new to arduino and i wanted to make a little project
a found and wanted to make this mtg life counter
but i want to this this lcd shield
i can make the screen to work but not the buttons....be easy with me pls its very new to me
all the help is much appreciate
that shield a single analog input to know what button is being pressed also there a libraries that need to be added. if you are new, I would recommend following instructions and doing exactly what they say with the same parts. that way if you need help you'll most likely get it because the instructions can be shared.
i add the libraries to the sketch the ones that i found in dfrobot site tried some different from the internet no luck,i cant understand how to modify the sketch to add the analog buttons...
Hi,
Welcome to the forum.
Please read the first post in any forum entitled how to use this forum.
http://forum.arduino.cc/index.php/topic,148850.0.html then look down to item #7 about how to post your code.
It will be formatted in a scrolling window that makes it easier to read.
Thanks.. Tom.. 
post your code (properly) that way we can see it
this is the original code

for the single analog input you need to have "int" for each analogRead value then assign them to like you would with a digitalRead….
if you look up a youtube channel called "the workshop" he has a working with LCD tutorial that discusses the shield you want to use.
