Sorry i will get the hang soon
Only be sorry for not asking questions!
This stuff (electronics, Microcomputers) is always like this in the beginning. Invisible things don't work. Slow down and check stuff out. Check the site you bought the LCD shield from for more detail on use and examples..
And, "Electricity Is Invisible", so buy a cheap LCD Multimeter if you don't have one ($5 on Ebay)..
I have some beginner stuff on a website: http://arduino-direct.com
don't repost this for now: user=kaust pass=student as It's Unfinished!
