I am proud to present a new release of Visual OPC Builder with Yun Support!
You can use it, link with some visual control and watch real time updating values from your Arduino.
You have to upgrade your monitoring library from https://github.com/SoftwareTools4Makers/OPC and use some samples to learn how to use it (p.e. https://github.com/SoftwareTools4Makers/OPC/blob/master/examples/Random_yun/Random_yun.ino )
Download Visual OPC Builder from project page at http://www.st4makers.com/vob
Please, use this forum to get support from the users comunity.
All the best
