IKEA makes pretty ghost-shaped night lights, but the power cable of these "SPÍKA" is very thin. One children has torn this cable and called Yoctopuce for help. At first, we thought that we would simply fix the power cable but, in the end, we decided to improve this night light by transforming it into a "connected night light" with a Yocto-Color-V2 and a YoctoHub-Wireless-SR.
From the start, sensors and actuators produced by Yoctopuce are USB devices. But you can enhance them with network connectivity very easily thanks to the YoctoHubs. As part of our "Yoctopuce for beginners" series, we are going to have a look at these YoctoHubs and discuss their advantages and disadvantages.
A few years ago, we explained why the Yocto-Watt is limited to 16A and we gave you some clues on how to measure high currents. But, at that time, we didn't have a simple solution to offer for the most current application: measuring and transmitting the main consumption parameters of a power distribution panel. This gap is today filled and we offer you a detailed solution, easy to implement, based on commercial components.
From time to time, some customers complain that the Yocto-3D-V2 lacks reactivity. But each time, it's due to a misunderstanding of our API. Indeed, to use the Yocto-3D-V2 efficiently, you must imperatively use callbacks. To illustrate this issue in an entertaining way, we have decided to show you how to correctly use a Yocto-3D-V2 in a Unity 5 game engine.
This week, we are going to tell you how we built an autonomous light beacon based on a Yocto-Color-V2. The idea was to take advantage of the pre-programmed sequences of this module to produce light effects which can be seen from far away.
