There is one and only Arduino :-)

I have not posted for a while but this is such a great news : after a long dispute which begun in 2015, a first “reconciliation” (Two Arduinos become one) in october 2016, it Arduino is moving forward

“BCMI, the company founded by Massimo Banzi, David Cuartielles, David Mellis and Tom Igoe, co-founders of Arduino, announces that today it has acquired 100% ownership of Arduino AG, the corporation which owns all of the Arduino trademarks.”

“Two Arduinos become one”…

I have not publish any article lately… but I just discovered the news this week a month late ! And I think it is definitely worth spreading the word.

Arduino LLC (running and Arduino SRL (running are on the way of reconciliation ! And that is, in my opinion, a very good news,

As said in blog post :

At the end of 2016, the newly created “Arduino Holding” will become the single point of contact for the wholesale distribution of all current and future products, and will continue to bring tremendous innovations to the market.

In addition, Arduino will form a not-for-profit “Arduino Foundation” responsible for maintaining the open-source Arduino desktop IDE, and continuing to foster the open-source movement by providing support for a variety of scholarships, community and developer initiatives.

How did I miss this !

Discovering Blynk… and making it work on DFRobot WiDo

I discovered Blynk last week.



Create an app for any connected project or product based on Arduino, Raspberry Pi, ESP8266 and other hardware


I saw it could work with Adafruit CC3000 breakout board… and WiDo is working with this library. So lets test it !

  • Grab a WiDo
  • Add the proper libraries
  • Connect 3 leds to the WiDo on pin 11, 12 and 13 (but any other pin will do !).
  • Download this sketch
  • Rename config.h.sample into config.h and customize the values depending on your environment
  • Upload  on the WiDo (don’t forget to specify the proper board : it’s a Leonardo clone)

And that’s it !

You’ll notice the code is rather simple : almost all the magic happens in whicg updates the led status when you press a button on Blynk App and a bit in Blynk.virtualWrite() which sends a value on virtual pin 1 and is used to blink a virtual led.

Received my WeIO :-)

A few weeks months ago, I participated to WeIO funding on Indiegogo. And after (patiently) waiting, I eventually got my WeIO board a week ago !WeIO 640Now, after struggling a little bit to configure it (I have no Wifi on my desktop PC and there is no instruction on how to configure the damn thing without Wifi), I am now going to test the gizmo and see what I can do with it !

A new WiFridge for a start ?


WiDo : a WiFi connected arduino

After presenting WeIO, here is WiDo from DFRobot, yet another Open Source IoT node.

It is basically an Arduino Leonardo which includes a WG1300 WiFi chip. Apparently, this can be used with Adafruit’s CC3000 Arduino library which should make it quite straightforward to use.

What’s the difference between an Arduino + a CC3000 shield then ? The price ! At less that $30, it makes a quite cheap IoT plateform !

Ordered some… (DHL shipping is free until the end of september) but no more in stock. So I don’t know when I will receive them 🙁
