====Change Node====

The **Change** node is a [[folder_logic|Logic]] node that is used to detect if a value has changed.

This is a slightly simpler method than using a comparison between [[ardi_point|Point]] and [[ardi_ppoint|Previous Point]] nodes.

This node is used in all [[analytic_modules|modules]].

===Inputs===

**Value (Input #1)** is a //number// value.\\

===Outputs===

**Output #1** is the a //true// or //false// value. When the value has changed, it will be **true**. If it's the same (or within the **tolerange** amount), it will be **false**.

===Options===

**Tolerance** is the amount of change that will be ignored by the node. The total amount of difference must be this high or greater in order for the output to change to **true**.
