There are three concepts in Rockpool:
Inputs get a value from somewhere, usually a button on a module or a sensor value
Outputs send a value somewhere, like a motor, a light, or a display
Converters change a value, either by tweaking it directly or comparing it to another value
To add a rule, click Inputs, Converters or Outputs and pick a starting point
Next, click one of the slots on the rule to change what it does!
Some converters want a comparison value, this will automatically create a new rule which you can tweak like any other.
