We discovered somewhat by chance the ADH-Tech GT-521F52 fingerprint reader. As it is really affordable, less than fifty US dollars, we decided to buy one two, to see what we could do with it.
Some time ago, we published a Node-RED node which allowed you to use a Yoctopuce sensor in a Node-RED schema. This week, we publish other nodes which enable you to use Yoctopuce modules other than sensors, such as Yocto-Relays, Yocto-Buzzers, and so on.
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.
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.
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.
