As you have learned in the Using the App guide, you can use Logic Nodes to add more logic to the data passing through the system.
When you tap on a Logic Node, you’ll see its programming grid (sometimes referred to as a “Logic Crafting Board”):
To learn how to perform basic user interactions with it, refer back to the Using the App guide. This section will focus instead on how to use each Logic Block.
For a reference list of what each block does, consult the Logic Blocks Reference List.
For some useful example programs constructed out of a set of logic blocks, consult the Example Logic Node Programs.
