The Loop Action makes actions within it reiterate a number of times equal to the length of the loop from its start value to end value. This action can be useful when you want actions to repeat. The example above pulses the output 1 for 1.5 seconds 5 times.

Creating a Loop with a variable

When using a Loop, the first value when creating a loop can be used to define a variable name. This can be used to make a loop address different things each time the loop iterates. An example of this is in the picture above, which declares a variable in the loop and sets the Relay that will pulse as it goes through the loop. This will make outputs 1 - 5 pulse for 1.5 seconds, one at a time.
