A node’s configuration can be edited by double clicking on
the block. If a node has any undeployed changes, it displays
a blue circle above it. If there are errors with its configuration, it displays a red
triangle.
Playground
The playground is a hosted instance of a customized version of the open
source, Node-Red . On the left you will find the palette with all the blocks.
Once you have created your program, the Deploy button on the top right
corner will be used to update and save all your changes.
Blocks or Nodes
Blocks are the basic units of creating logic. There are many blocks for different
functions in the palette. Blocks can be added to the workspace by dragging
them from the palette.
Wire
Nodes are wired together by pressing the left-mouse button on a node’s port,
followed by dragging to the destination node and releasing the mouse button.
