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.
