Many of you were with us last October in Rome for the European Maker Faire together with more than 500 makers from all over the world! The event was massive and 90 thousands people visited the booths, the workshops and the presentations taking place in those days.
To celebrate the amazing moments we created a series of short videos showcasing the use of Arduino in projects hosted during the Faire. Our crew explored the whole exhibition and talked with a lot of makers presenting a project with Arduino inside. We asked them four simple questions:
- What have you built?
- Which problem does your project solve?
- Why did you use Arduino as a controller
- How long did it take to make it?
We recently posted on Intel Makers Community the first of a series of educational tutorial focused on Intel Galileo Gen 2. Our team worked on a smart Christmas star able to receive sms and change pattern according to it. The bill of materials contains also an Arduino GSM Shield, a Proto Shield and some flexible LED strips: Read the rest of this entry »
It’s going to be a great weekend in London in mid January. Massimo Banzi, Arduino co-founder will be at the Somerset House in London for three days. The program starts with a talk followed by a Q&A, on Friday January 16th in the Screening Room, South Wing at Somerset House. (book your ticket here)
On Saturday 17th, and Sunday January 18th you can take part to two 8 hours sessions that will be held at Makerversity, in the New Wing of Somerset House. The workshop is suitable for beginners, designers, teachers, artists, hackers, and everyone interested in Arduino (no prerequisites needed). At the end of the two sessions each participant will be able to prototype autonomously a simple project with Arduino. The participation is available for a max of 20 people: you can check details and book your ticket here. The presentation taking place on Friday is free for workshop participants.

May I introduce my second ARDUINO-project with own pcb. With the pcb I am able to drive seven brushless pumps(with integrated electronics). The “problem” with such kind of pumps is that they don’t accept unfiltered pwm-signals as supply voltage. So I created a circuit where the pwm-signals of an ARDUINO-micro are level-shifted to 12V with a darlington array and afterwards filtered with a 1 uF ceramic capacitor and a 730 Ohm resistor (low pass filter). The signals are then led into the adjust-pins of seven “lm317″s. To work properly I needed to connect the adjust-pins also with 2500 Ohm resistors to gnd, but I found out that with two l293d instead of the used TDP62783 (darlington array) these resistors are not needed, but different resistor and capacitor values for adequate filtering!
The pums also have tacho signals which I connected via schottky-diodes to the ARDUINO (inputs with pullup). With the tacho-signals I am able to find out if pumps are stuck, are sucking air or are not connected.
Additionally I added one ACS712-05B current sensor (which measures the entire current of the circuit) that could be used to find out if pumps that don’t have tacho-signals are working properly. At the moment it is not used.
Besides that I integrated a lm386 audio-amp used to amplify the signal of an electret-mic to a level that is suitable for the ATEMGA’s ADC.
As the first project for the pcb I created a fountain consisting of a shortened wine barrel, seven brushless pumps, a pushbutton with led and pebbles (s. video).
There are seven animation-modes which can be selected via the pushbutton (the selected mode is stored in eeprom).
The speed of the pumps is checked permanently during operation.
The average power consumption is ~20W and max. consumption is 30W.
Last saturday, Arte tvl aired a short documentary in french language about Arduino. The video was created by FUTURE magazine and featuring Massimo Banzi, David Cuartielles and Arduino users: children and young electronics enthusiasts:
Tinkering in a garage on a drone, playing with a set of lights with LEDs or even build a robotic arm worthy of a science fiction movie … Today, even when one is a novice in electronics all this is possible through Arduino, a real flexible technology.
30 Arduino TRE Developer Edition boards (the last ones!) are available online today on our store. Whoever purchases them will be added to our Beta-testing Program, joining the about hundred betatesters already contributing to the development of the hardware and software of the board.
UPDATE, December 15th: the boards sold out over the weekend and are no longer available on our store.
You can learn about the program and the board on this post. These boards have the latest Web IDE pre-installed and ready to go, we are now at a stable IDE release with everything fully functional. We will write a specific post about the new Web IDE next week, so stay tuned!
The first round of the program focused mostly on hardware and software testing, and we have just rewarded the betatesters who contributed the most. We really would like this second round to revolve around contents creation. For all Arduino boards, examples and projects are really crucial to get beginners started with a new environment. This is even more relevant for the Arduino TRE, that thanks to the onboard Linux system, has so much more power and potential than classic Arduinos.
For instance you could use the Arduino TRE as a personal cloud, keeping all your data available to your connected devices without having to rely on third party services; you could create a system to stream music wirelessly to your speakers with a tangible user interface; build a DIGI software that allows ZigBee porting; make an interactive whiteboard for schools, and so on.
We have a reward system in place for completed projects: two coupons of the same value of the Arduino TRE Developer Edition purchased, a dedicated post on our blog, Arduino TRE limited edition T-shirts, 10% off coupons for the Arduino Store. We look forward to hear about your projects!
When is the Arduino TRE going to be finally on the market? The board is ready, but we don’t have a final release date yet because we are still figuring out some manufacturing matters. We’ll keep you posted!

3D Photobooth, Xun Yung and Tien Pham, Maker Faire Rome 2014.
A 3D anaglyph photobooth uses two cameras to capture a 3D picture. Each picture is processed using the Arduino TRE board. It separates the red channel from one camera and the cyan channel from the other, and overlays them together. The result is then printed out on a large photostrip.
Last week we published four gift guides presenting a list of products available on the Arduino Store and organized by topic: for Kids, and for people interested in IoT, Home Lab and Fashion Tech.
Now we’d like to give you some suggestions for gift ideas fitting anyone’s piggy bank:

It’s a tiny AVR-ISP (in-system programmer) based on David Mellis’ project FabISP and useful to anyone needing more space on the Arduino board.
Flashing Card Set – Merry Resistivities by Bare Conductive
The Merry Resistivities Set contains all the materials you need to make three flashing greeting cards using Electric Paint. This fun activity is great for makers of all ages.
A simple POV toy for beginners who wants to learn how to solder, how to program microcontrollers, or to make LED blinking toys. Because the programmer is built into the kit, one does not need a special “microcontroller programmer”.
