To use this node in your Embrio project, either add it from the Library toolbar or copy the XML in the below box and paste it into a node screen.

This node demonstrates how to write to an LCD in two different ways. First, an input text value is written to the first line when a trigger fires. Also, an input activation value is printed on the second line every time it changes.

Getting these LCDs can be tricky, so it’s advised that you make sure everything is working by running the “hello world” Arduino example.
