The Yocto-Color and RGBW leds

By martinm, in New stuff and Programming, april 06,2018.

The Yocto-Color-V2 was designed in the beginning of 2016 to drive those small RGB leds that one can wire serially and address individually, the most well known ones being the Adafruit NEOPIXEL leds. Meanwhile appeared the RGBW leds, which can emit not only red, green, and blue but also white and which are, for sure, compatible with the classic RGB leds. Good news: we just published a new firmware for the Yocto-Color-V2 which drives these RGBW leds.

Larson scanner

Do you know the commonality between the TV series Battlestar Galactica (1978) and Knight Rider (1982)? Actually, there are at least two: their creator Glen A. Larson, and this small chase effect in the Cylons visor and at the front of KITT, hence the "Larson scanner" expression. We wondered if we could do the same effect with the autonomous animations of the Yocto-Color-V2.

About programming examples

By martinm, in For the beginners and Programming, january 12,2018.

From time to time, Yoctopuce support receives emails from customers who complain that the examples provided with the Yoctopuce programming libraries don't work. We don't pretend to believe that our code is 100% error free, but it is clear that, most of the time, the problem comes from a misunderstanding about how these examples work. This week, we are going to clarify this issue.

Adapting monitor brightness automatically

By seb, in Programming and Misc, december 08,2017.

This week, we are implementing a program suggested by one of our customers: Using the Windows API to adapt the brightness of a monitor depending on the ambient light. Most laptops already do that, but desktops don't because they don't have a light sensor. We are going to use a Yocto-Light-V3 to determine the ambient light.

How to begin with the data logger of Yoctopuce sensors

By martinm, in Programming and For the beginners, october 20,2017.

Almost all the Yoctopuce sensors are equipped with a data logger. We already wrote on this subject several times, but this week we give you an overview in the framework on our for the beginners series. Follow the guide...
