I bought a Maplin serial lcd the other day. I have wired it up as per instructions (RX goes to pin 2 of Arduino) but can’t communicate with it.
The display lights up, and the screen shows a brief splash screen message from the maker (LinkSprite.com), but I can’t print anything to the screen.
I have attached the sketch I am using. Must be something simple, I think, but I can’t see what is wrong.
Grateful for any help.
