====Change Node====

This is a [[module_count|counter]] node. It adds **1** to the count **every time the input value changes**.

This is often used when you want to count the number of times a specific, relatively slow (ie. lasts for more than 1s) event has happened.

Note that this node will count **any** change in value. If you only want to count a //specific// change (such as when it turns //on//), you should use the [[counter_ignore|Ignore]] node.

For an example of how this operates, see below.

This node is only available in **counter** [[analytic_modules|modules]].

===Inputs===

**Input #1** is a //number//. If this value has **changed** between samples, the count will be increased by 1.
