LabVIEW Beat Pattern Detector (Door Knock)

[niNickC]

Overview
This example VI is that it detects a pattern of mouse clicks which regardless of tempo to open the door.

Description
This VI built a nice little event based, producer or consumer architecture. Each time the mouse is clicked, it queues up the time, the consumer then calculates how long between it and the previous click. Once 3 clicks have been hit, the program knows the tempo the user is going at and uses this information to see if the next clicks happen at the right time. There is a timeout case which resets everything in case you get it wrong!
