Arduino boards are able to control small motors very easily and it’s just as easy when you have to deal with controlling large motors. In the following video tutorial by NYC CNC you’ll see two examples. In the first you’ll learn how to get up and running, to start, stop, control direction and speed of a large motor with Arduino Uno. In the second example, how to use two proximity sensors as limit switches and two potentiometers to allow on-the-fly speed adjustment.
Have you ever wanted a smart home that can automatically adjusts the blinds for you? If so, this project is for you.
In this instructable, the author describes his approach to “smart blinds”, by using an Arduino board, an ethernet shield, a motor shield and a couple of sensors.
By means of a simple web-based GUI, the user can manually open and close the blinds, or he/she can setup both temperature and brightness thresholds in order to automate the whole process. Finally, opening and closing events can also be scheduled at pre-defined times of the day, if necessary.
The complete tutorial, together with the source code of the project, can be found here.
We are eager to announce the launch of the official Arduino Starter Kit! We have been working hard together in developing a complete selection of 15 projects that will let you become a true arduino tinkerer!
But that’s more:
The new starter kit has been developed together with a series of ten video tutorials hosted by Arduino co-founder Massimo Banzi, which can be viewed at www.rs-components.com/arduino. Ideally used in conjunction with the videos, the kit provides an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It contains all of the essential components required to start programming with the Arduino Uno board, and a guidebook featuring 15 different projects, which are designed to evolve the user from beginner to professional level. Comprising a motor, servomotor and driver, the kit also offers particular benefits to users wishing to apply mechatronics to their designs.

We are aware this kit will let a lot of people step in the Arduino world: for this reason we opened a brand new category of the arduino forum. You can buy the Kit on RS Components and will soon be available on the Arduino Store and the other distributors [notify me when this happen]
Open Electronics‘ staff were looking for a common and standard hardware platform usable on different robots they were working on. Their goal was to find a single platform that had to provide power supply to the microcontroller, it had to provide stabilized voltage for the servos, and, finally, it had to be equipped with an obstacle detector and with an IR receiver.
Having chosen Arduino as the target core board, they developed an ad-hoc shield meeting all these requirements, whose detailed description can be found here, together with the BOM and a lot of source code.

Nice Grasshopper-to-Arduino plotter hack from FablabTorino maker Pietro Leoni, a collabotator at Carlo Ratti Associati studio in Turin. We’d love to see code & sketches online soon, as much as a second edition of the plotter.
From his website:
2012 is not only the year of the Olympics, but also the launch of the first ever ‘Digilympics’, a twitter-powered race for sporting success where you determine the outcome. Four Lego athletes move down a physical racetrack as fans Tweet their team to move them further towards the finish line.
Starting today (07/18/2012), the Digilympics will be a two-week event as the four teams – UK, US, Canada and Japan – compete for the prestigious Digilympics Gold Medal.
The competition is open to anyone on the web, allowing them to Tweet their team to success using one of four unique Twitter accounts (UK_Digi, US_Digi, CA_Digi &JP_Digi). Tweets in support of a particular account will move that country’s contestant physically along a running track.
After each race, the team victories are recorded and contestants go back to the starting line. At the end of the week the team who has won the most races will be given the Gold Medal online at digilympics.com
Under the hood, this funny race is enabled by a Processing sketch that seeks for Twitter replies on each account: a new reply triggers a motor-shield equipped Arduino board, which provides the movement to each athlet.
More information can be found here. And… let’s start twitting for your favourite team! ^^

We are happy to announce the first wearable kit on the Arduino Store . This kit has been made by Plug’n'Wear specifically for us. All fabrics in this kit are produced in Italy, and strongly related to a textile family business. If you want to get deeper into the story of this product have a look at Riccardo Marchesi presentation (still in Italian, soon to be traslated!) at World Wide Rome 2012.
Read over for Kit’s features
This kit features:
- 1x Circular Stretch Sensor Designed by Hannah Perner-Wilson, this circular knit stretch sensor works perfect when you need to detect tension in many projects.
- 2x Textile push button to make easy digital inputs in cloth, scarfs o bags.
- 2x Spools of Conductive thread, ready to be hooked over a sewing machine
- 2x Soft potentiometer kit will let you import analog data into your wearable project: this kit includes 1 meter of knitted conductive tape and a metal ring. Watch it in action (see video)
- 10x 1k ohm resistor
- 10x 10k ohm resistor
- 1x Textile perfboard is going to change the way you think of wearable circuits. You can sew or even solder components (SMD & through-hole) on this . It can be easily cut or sewn with a standard sewing machine. Washable. Size: 15 cm x 15 cm (6″ x 6″) / Pitch: 2.54 mm (0.1″)
- 1x Knitted Coated Copper Tape. Small conductive tape made of coated copper fine wire (112 micron). Flexible, easy to cut, sewable with a standard sewing machine, It can be easily welded ( The coating will melt and tape will be soldered). The surface of this tape has a good insulation thrughout its lenght. Resistance: 107 Ohm/m. Width: 9 mm (0.35″)
- 1x Analog Textile Press Button, working with a resistive principle (resistance goes down when you press it). It works as a bend sensor as well. By connecting more sensors together it is possible to make a matrix analog switch. Sensitive area 40mm x 40mm (1.57″x1.57″)
- 2x LilyPad LED Bright White A simple, very bright, 250mcd, white LED LilyPad
