If you want to build a USB control panel, you can probably find all the electronics that you need in the Yoctopuce product range. For example, the Yocto-Knob for buttons and potentiometers, the Yocto-PWM-Rx for quadrature decoders, the Yocto-Color-V2 for light signaling, and the Yocto-Buzzer for sound signaling. However, it was pointed out to us that as soon as you want to build a somewhat substantial control panel, that's a lot of USB modules to install in the same enclosure...
After having announced two weeks ago the preview of version 2.0 of the C++ library, here are version 2.0 of the C#, Python, and Visual Basic .NET libraries. They are also available as previews.
Several customers asked us in quick succession whether the Yocto-Color-V2 was compatible with RGB WS2811 leds. In theory, the answer should be no, but as we like to please, we made the necessary modifications so that it now works.
This week, we present the brand new Yocto-Light-V4. It is probably of interest to you if you need to measure the ambient light in a somewhat dark corner.
Linux is an OS which is widely used in the IoT. Unfortunately for the users discovering this OS, it can be quite confusing. For example, by default, Linux blocks write access to the USB devices for "non-root" users. It isn't really easy to configure an application so that it starts at boot time. This week, we are going to see two small improvements which are going to make the life of Linux users easier.
