Program a Yún without writing code! Temboo’s Sketch Builder

Sketch Builder - Sensor Selection

Today’s guest blogger Vaughn Shinall from Temboo‘s team updates us with a new feature to ease your way into smart homes.


Choose your sensor, choose what action you want it to trigger, and voila–your  Arduino Yún is doing it. Sending texts when a light sensor detects night, logging temperature data to a Google spreadsheet while you’re away, calling you when it sees an intruder in your home.

With our new Sketch Builder you can program your Yún to do all these things and more in no time. After choosing from multiple sensor types and actions, you can set the conditions and pins for your set up and have the code generated in an instant right on Temboo’s website. Then it’s just a simple copy-paste-upload job, and you’re on your way. (more…)

Build an Arduino Yún powered cat camera

Arduino Yun

Hotte submitted to our blog a tutorial to monitor his 2 little cats in their favorite spots when he’s  at work:

This is a very, very small project that shows just how to build an Arduino Yún powered Camera application: It grabs photos from an USB camera connected to the Yún, saves them periodically on a uSD card and uploads them to a web host where a gallery is automatically created based upon the number of images in the upload folder. This project might be for interest for people that are just getting started with the Yún and want to explore more of its capabilities…

Every 5 minutes the Arduino Yún grabs pictures from a connected USB Webcam and saves it on its micro-SD card. From there the newest photo gets uploaded automatically to this webspace here where a little script transforms all the pictures in one folder to a photo gallery. The optional step adds an PIR motion sensor to get a snapshot if anything moves. (more…)

Arduino Yún at Open Thesis Fabrication

Wednesday, January 8th, 2014

OTF at Iaac


The Arduino Yún has been used by IAAC‘s  Open Thesis Fabrication student Marisa Charusilawong to make an interactive toolkit for developing interactive facade elements using shape-memory alloy. During the 16-week intensive research program based in Barcelona:

We developed a modular system where several Arduino Uno’s can be networked over I2C and finally connect them to an Arduino Yun where a simple REST API is exposed allowing application to interface the system to manually actuate on the structure and to set the different behavior modes. Because Yun’s rich API capabilities we will be able to connect to other API’s to retrieve real time weather and environmental data on a near future.

The electronics were assisted by Physical Computing expert Guillem Camprodon based at IAAC – Fab Lab Barcelona who also wrote us: (more…)

Arduino Yún with sound the supereasy way

Arduino Yún



During Codemotion Milano Stefano had a talk with Federico Vanzati from Officine Arduino on how to use a supercheap USB Audio card with Arduino Yún and test the full audio capabilities with zero effort, external libraries or mp3 shields.

After some days he came out with a quick tutorial that you can check out here (includes code!).



Controlling water heater with Arduino Yún

Thursday, October 31st, 2013


This week I’m going to introduce George Koulouris who loves playing, testing, making with others  especially at the ‘Petit Fablab de Paris’ where he thinks is a  great place to do exactly that!  He’s been experimenting with the Arduino Yún focusing on his main interest: the integration of technology to everyday objects. The following post was originally posted on his blog Read  other guest posts on Arduino Yún.

The Motivation
I have two small problems in my house. An ever-increasing electricity consumption bill and a girlfriend which likes to take hot baths at unpredictable times during the day.

Until recently, we left our water heater switched on, 24/7. But then we took a look at our electricity counter readings. Needless to say, we switched it off immediately! An old water heater can indeed make the electricity counter wheel spin fast, very fast…!

So we started switching it on and off whenever we needed to take a bath. The problem was that we weren’t always at home and the water took almost an hour to heat-up! So I decided to connect it to the internet! (more…)

Making a RFID Card Reader with Arduino Yún

Arduino Yun
Surya Mattu is a creative technologist who loves to make things. He’s based in NYC and working at ITP, a two-year graduate program exploring the imaginative use of communications technologies. Today he’s sharing with us how feasible it could be to build an RFID-controlled entry for students using Arduino Yún. Read  other guest posts on Arduino Yún.


I work at ITP as the student floor-staff programmer. At the start of the semester I was asked to set-up a system to allow students entry to the ITP floor from the fire escape using their university cards. Although this is something that would normally fall under the NYU IT departments domain its a long and arduous process involving lots of different departments so we decided to go with something that was developed in-house.

Although this is a relatively simple task it has a few steps that can be clunky. The objective was to design a simple solution that doesn’t require much maintenance. (more…)

Arduino Yún as a possible Mesh Extender Platform

Serval Project Yun

It’s great to have Paul Gardner-Stephen as the guest blogger of today after he spent some days in experimenting with Arduino Yún . He’s based in Australia and the founder of Serval Project, making tools to let people communicate without carriers by enabling smart-phones to talk directly to one another to form Wi-Fi mesh networks and “Mesh Extenders”, allowing a single unit to cover hundreds of homes, even in urban areas. We like their motto:

“Communications should not just be for the geographically and financially fortunate — communication should be freely available to everyone”


Regular readers of my blog will know that we have been looking at a variety of hardware options for the Serval Mesh Extender.

The Serval Mesh Extender is a device that combines ad-hoc WiFi meshing with long-range license-free UHF packet radio to allow the easy formation of mesh networks spanning useful distances. Typically the UHF packet radio has a range about ten times greater than WiFi. This means that in ordinary suburban and urban areas we get a range of a block or two, and in open rural areas the range can be in the kilometres.

We run our award winning Serval Mesh software over the top, providing an easy to use communications system that lets you use your cell phone without cellular coverage, for example, during a disaster, or when you and your friends are near one another outside of the range of your native network. For example, if you are at an international gathering and don’t want to pay $4 a minute for the privilege of calling someone a few hundred metres away. (more…)

Getting started with Arduino Yún video tutorial

Getting Started with Yún


The Arduino Yún is an Arduino board unlike any other. While programming it is very similar to the Arduino Leonardo and uses the same processor, the Atmel ATmega32U4, it also has an additional processor, an Atheros AR9331, running Linux and the OpenWrt wireless stack. Programming the 32U4 via USB is identical to the Arduino Leonardo. Once you’ve configured the Yún to connect to your WiFi network, you can program the 32U4 via WiFi as well.

We prepared a video to explain how to take the first steps with the board, you can watch it below and then keep reading the Getting Started Guide:



The Yún Way: less time debugging and more time inventing

Back then secret device, back then secret Yun.


Today I’m happy to welcome Sven Kräuter as guest blogger on the Arduino Yún, as part of a series of posts exploring different unique features of our new board.

Sven works with Julia Kümmel focusing on agile & lean processes for soft- and hardware product development and together create projects at the intersection of the physical and the digital world, mostly using Arduino. His post below was orginally published at this link.


This summer I had a speaker engagement at the Codemotion conference in Berlin which I really enjoyed for many reasons. For starters Jule & me participated in an inspiring wearable computing workshop where we met Zoe Romano for the first time. The next day I talked about a possible and easy way how to build the internet of things.

Presenting thoughts on & actions how to build the IOT.

After the talk it seemed to appear like a a good idea to Zoe that I should get a sneak peek at some new Arduino hardware. There weren’t any more details since it was still secret back then. Of course it didn’t took me much time for consideration since I really love Arduino for making our hardware prototyping so much easier. I happily agreed on checking out this new mysterious device.
