Five years ago, we modified our Jura coffee machine, which we nicknamed Josephine, to control it remotely via a web page. The idea was amusing but in fact this feature wasn't really useful as we still had to get up to place a cup in front of the coffee machine. But today, thanks to the Yocto-Proximity, we can do something more useful: We are going to brew a coffee as soon as a cup in placed on the machine.
Node-RED is a visual programming language that can be used to connect various Web services, API or peripherals together. Node-RED can use data coming from a Web server, a MQTT broker, a mail server or even Twitter, but not from Yoctopuce sensors. That is, until yesterday...
Last year, Microsoft announced the Azure IoT Suite. Behind this somewhat pompous name hides two examples of use of their Azure cloud with connected objects. We are going to see how to use Yoctopuce modules in one of these two examples.
This week, we present a small and quite simple DIY project based on the fact that white ping-pong balls make excellent light diffusers. We built a kind of multicolor chandelier, that you can drive through the Internet and which is PoE powered.
The Yoctopuce business model is rather simple: Yoctopuce designs, manufactures, and sells electronic modules, provides the libraries necessary to exploit them, as well as support to help customers realize their projects. However, Yoctopuce doesn't provide turn key solutions. Nevertheless, Yoctopuce support regularly receives requests of the type: "How can I display a graph with the values of a Yoctopuce sensor?", or "How can I obtain the values of a Yoctopuce sensor in the CSV format?". So we decided, once will not hurt, to offer you a ready to use application to trace graphs with the values of Yoctopuce sensors.
