LabVIEW Donut Counter

Ken Sharp, April 2016

Summary

This project is an example application for LabVIEW running on a BeagleBone Black. It reads a photocell sensor located inside a donut box to sense when the box is opened. Each time the donut box opens and closes a counter is decremented to indicate that a donut has been taken. The application also uses LabVIEW web services to serve a web page which displays the current donut count.

Application Site Map

• /ws/donut.html - main page
• /ws/GetCount - web service to get current donut count in JSON format
• /ws/SetCount - web service to set count (for instance when donuts are loaded in the box). Query string should be of the "count=5" to set the counter to 5.
