Free geolocalization using Leaflet

By mvuilleu, in Programming, may 12,2018.

OpenStreetMap logo by Ken Vermette [CC BY-SA 2.0]Two years ago, we showed you how to geolocalize a vehicle without using a paying service, with a Yocto-GPS and the Google Maps API. But this month, Google decided to make the use of the Google Maps API billable. This gives us the opportunity to have a look at alternatives based on free and collaborative development, which no longer have anything to envy Google.

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.

Larson scanner

By martinm, in Programming, february 23,2018.

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.
