Variables

Variables store and manage data in your scripts. Use variables to track changing values like sensor readings, counters, states, or calculated results.

Create variables through the Variables section in the toolbox before using them. Variable names are case-sensitive - choose meaningful names to make your code easier to understand.

Managing Variables

The variable dropdown menu in each block provides options to:

• Select existing variables from your script

• Rename the selected variable (updates all references)

• Delete the selected variable (removes from all blocks)

Renaming or deleting a variable affects all blocks that use it. Be careful when modifying variables used in multiple places.
