Making a smart extension cord

By seb, in DIY, september 22,2023.

This week, we're going to do a little DIY. The aim is to make a "smart" extension cord that measures consumption and can be controlled remotely using the WiFi network.

Sending values with communication modules

By mvuilleu, in New stuff, september 15,2023.

Yoctopuce serial communication modules such as Yocto-RS485-V2 and Yocto-I2C are capable of autonomously executing small communication protocols, for example to interrogate sensors. We were recently asked whether it was possible to use a value received from a sensor in a message sent later. As is often the case, the answer is: yes, it's now possible...

Web page, Yocto-Visualization, and actuators (continued)

By martinm, in Programming, september 08,2023.

Three weeks ago, we showed you how to integrate code on a web page that manages Yoctopuce actuators while using Yocto-Visualization (for web). But there was one limitation: we couldn't use the DeviceArrival and DeviceRemoval callbacks because they were already used by Yocto-Visualization (for web), so the code was a bit rickety when it came to checking whether the actuators concerned were connected or not. As this was a bit of a problem for us, we've slightly improved Yocto-Visualization (for web)...

Using TLS/SSL with our PHP library

By seb september 03,2023.

Our PHP library has supported SSL/TLS encryption for several months now. This makes it possible to use the library to connect to VirtualHub v2.0 and VirtualHub for Web. Let's take a look at how to use this feature to establish a secure connection between the library and VirtualHub.

Rotary knobs with quadrature encoder

By mvuilleu, in New stuff, august 25,2023.

The Yocto-Knob and Yocto-MaxiDisplay variants have analog inputs for connecting interface buttons: pushbuttons, rotary knobs. However, there was one type of button that was not supported: infinite rotary buttons with quadrature encoder. This limitation has now been lifted.
