can never get a LCD to work with UNO

floresta:

Just try the line

LiquidCrystal lcd(8,9,4,5,6,7);

Don't be tempted to re-write the number in order.

This is horrible advice.

Your recommendation points out the fact that you really don't understand it's purpose. Why don't you follow the links in reply #9 to find out?

No it isn't, I understand the purpose well, and it is very good advice.

I say this because:

  1. While I have not read reply #9, I have read the original post, which I recommend to you, and the problem is very much like the problem I had, right down to the source of code that could be problematical.

  2. The advice I gave actually works. Well, it did for me, indeed it is all I needed to do.

The advice was well-intended and simple enough to try, hopefully Knuckles will get the same result and, in that blessed event, we will all be glad to hear from you.

Oh, and guess what? I have also read the good news from Johannesburg in reply #8, which I also recommend. You might find it as entertaining as I do, although I guess you will not find it a pearl of wisdom.
