Implementing a hanging scale

By seb, in DIY and Android, may 04,2018.

This week, we are going to do some tinkering and build a hanging scale with a Yocto-Bridge and an Android smart phone. The aim is to weigh objects ranging from a few hundreds of grams to about twenty kilos, in order to weigh objects such a model air planes or bikes. Strangely, two widely popular hobbies at Yoctopuce :-)

Test of the GT-521F52 fingerprint reader

By martinm, in Reviews and Programming, april 27,2018.

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.

Improvements for the Yocto-PWM-Tx

By mvuilleu, in New stuff, april 20,2018.

After four years of operation, we rejuvenate the Yocto-PWM-Tx this Spring, with hardware and software improvements. It naturally stays 100% compatible with the original version. Here is a small overview of what's new.

Our new Node-RED package

By seb, in Programming, april 13,2018.

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 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.
