This week, we show you how to build a bar lamp based on RGB LEDs. It's easy and you will end up with something almost as pretty as those you may find in your favorite appliance store. Moreover, each LEDs can be controlled individually, which is not a common feature among design lamps.
We sometimes have customers who ask us whether we have some ideas on how to check that a display supposed to show videos is actually on and works correctly. It so happens that yes, we have a few ideas :-)
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.
