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

Good news: we just published a new firmware for the Yocto-Color-V2 which drives these RGBW leds.
