Paperduino Pi

via Arduino Blog

This is a project for people a little bit skilled in soldering and design PCB. The user [dernulleffekt] designed an homemade shield for Raspberry Pi that integrate an Arduino Board.

The Paper-Duino-Pi is an Arduino shield for the Raspberry Pi. Due to the fact that it is designed as Paper-PCB it is easy to create and one doesn’t need a printed circuit board. Some small modificaten in the OS and IDE and you have a perfect interface for the Raspberry Pi.

This [video] shows how one can use it with the Firmata and Pure Data. On the [website] there is a very well written tutorial to build your Raspberry/Arduino shield at home.

Chat with Xbee for Arduino

via Arduino Blog


Thank you [priyansmurarka] to send us this project involving Xbee. This module is fully compatible with Arduino Boards and you can connect it with a proper shield, the [WirelessShield] . With that you can make comunicate Arduinos wireless, including sending messages about status or whatever you want. The submission of today is about building up a simple chat system.

It is a simple peer to peer chat system made using XBee radios which are compatible with Arduino .

On the [blog] of [priyansmurarka] you can find all the step to configure two modules and make them “talk”

Wireless Sensor Network for Temperature Sensing

via Arduino Blog

This is an interesting implementation of Arduino and Wireless comunication. The user [priyansmurarka] posted:

Ok, so here is the basic problem statement. I need to develop a temperature sensing system such that the temperature from the sensor node is relayed to a co-ordinator sensor and then the co-ordinator node shows the user in a simple graphical form.

For the wireless communication, I used Xbee Series 2 modules with Arduino Board Shields.

Uses Melexis Temperature sensor and Arduino Board to monitor and plot ambient temperature.

The realization of this project is well documented on the [blog], with code, graphs and pictures.

WhiteSpace TweetTrain

via Arduino Blog

Somebody knows how to have fun in the office and with Arduino. Have a look at this project by [whitespacers] powered with our boards

Christmas is a time of gathering the family around and enjoying the simple things in life. And what could be simpler than a good old fashioned train set… powered by tweets?

Tweeters can simply send a message to #tweettrain then enjoy the ride via the onboard camera streaming to as they puff their way round the Whitespace HQ Winter Wonderland.

The magic also lets tweeters control the Tweet Train’s direction and speed by telling it to go in ‘reverse’ or ‘fast’.

Iain Valentine, creative director and Whitespace Santa said: “When visual, digital and experiential marketing are linked effectively, it can seem like magic. We wanted to bring our clients something special for the festive season and so our elves were kept busy bringing the late 19th century Christmas gift of choice into the digital age. Deep down, everyone wants a toy train set for Christmas!”

If you’re wondering which particular type of Christmas magic we used; it’s the extra special Arduino-micro-controller coupled with a wifi receiver type.

You see Santa’s elves replaced the Tweet Train’s manual train controller with a wifi receiver so the train can be controlled by digital commands. Tweets containing the hashtag #tweettrain are searched for, simplified, and sent to a new URL that the arduino checks for new tweets. Each time it spots one, it powers the train motors. Magic basically.

We reckon it gives the Hogwarts Express a run for its chocolate money, but why not try it for yourself? Visit. Tweet. Drive the train. The station is in live cam on the [website]

Book Cricket

via Arduino Blog

Arduino is not just the chip, there is also the IDE that brings the same name and purpose. It’s open source and free, so you can use it on every microcontroller like the ones on Arduino boards. Here an example from India! Thanks [rahulkar] for submitting.

The project is a digital implementation of “book cricket game” which Indian students normally use to play in their childhood time. The heart of the project is 8 bit MCU from AVR family called ATtiny85. ATtiny85 are small and cheap microcontrollers which are convenient for running simple programs with low footprint. The software used for programming the MCU is Arduino.

If you’re interested there is a post on the [website] that explains all the step to build it, have a look!

How about a new way to make music? [cpeckmusic] has it’s way to do it, with is project Sharpy.

Sharpy is an electronic instrument that was designed and built by composer Charles Peck. The instrument utilizes three infrared distance sensors to control the sound, which is produced digitally with an Arduino board and GinSing shield. So as users interact with these sensors, there is a clear auditory connection to their physical actions.

Despite having only three sensors, the instrument is capable of a variety of sounds. This is because Sharpy has three possible operating states, each of which assigns a different set of parameters to the three sensors. State 1 is initiated by covering the sensor on the user’s left first. The instrument will then stay in State 1 until no sensors are being covered. Therefore, the user must completely remove their hands form the instrument in order to change states. Concordantly, State 2 is initiated using the middle sensor and State 3 using the sensor on the right. The short improvisation in this video demonstrates a few of these sonic possibilities.

I suggest you to watch the [video] of the live performance. If you’re interested in more works check his official [website]

Arduino Water Thermostat

via Arduino Blog

Arduino is not only for hobby projects, there are also good way to use it to semplify your work. This is a good example, submitted by [sspence65].

This is a project I did at work to control two water baths for a process control. Two custom tanks have to be kept at 180F, using DS18b20 temp sensors, an Arduino 2560, 4 SSR’s, and $15 1500 watt electric elements.

On the [website] you can find all about the project, included the code for the Arduino Mega.

Robocademy for Arduino

via Arduino Blog

This is a service that is starting and involves our beloved Arduinos and coding.

Robocademy allows anyone to upload code to currently two Arduinos and see the Arduino over live video. I started the project because I got to play with a robot over the internet and thought it would be great to let people program Arduino over the net. The code is completely open source, BSD license. I want to have people put their Arduinos online from all over the world.

Why don’t you give a try? You can find it here on the [website].

Pong Clock

via Arduino Blog


This is an original way to build custom digital clock. Thank [mrnick1234567] to send us this project, I suggest you to see the [video] to understand better the capabilities of this clock.

This is a year or so old now, but I though you might like to feature it. It’s a clock that plays the game pong to tell the time. It uses a couple of cheap LED matrix panels an Arduino and clock chip.

As the author says, all the instructions are on the [website],

“..and quite a few people have build them / modified my code to add other features.”

We hope they will submit their “mod”, I would be glad to post them in the blog.

3D SparkCube with Arduino(s)

via Arduino Blog


Here an amazing project. It’s a 3D projector “homemade” with Arduino. Many Arduinos and lot of LEDs RGB.

We build a LED cube with 4096 LEDs powered by 16 arduinos. It can show 3D animations, words, and just about anything else we want. It stands about 6 feet tall including the base and has over a mile of wire connecting it all together.

The full build log and images are hosted on the [website]. Thanks [tbennett] for submitting it

Arduino/Android Wireless Robot

via Arduino Blog

Another Robot, another App(lication) of Arduino. The user [shreks7] built up an Android App for controlling the robot wirelessly and stream live video off an android phone placed on the robot.

The robot has an inbuilt wireless router and two brush-less DC motors and runs on a power source of 26-30V(depends on the requirement) power supply.

The robot streams live video back to the app and can be used for navigation.
Also there is a console for Windows to control the robot and debug it .

It uses Arduino Mega 1280 + Ethernet Shield + Pololu Motor Driver (It is by far the best one i have used) + Belkin Router & Two Android Devices .

There is also a [video] where you can see the robot in action.

Arduino IR Remote Control

via Arduino Blog

This is a good example of hacking devices with Arduino. [sspence65] has put on oa good tutorial to start from something easy and simple: IR hack.

Capturing codes from any tv remote, and using them to control devices attached to Arduino Outputs. Press a button on a TV Remote, and the code appears in the serial monitor, Add that code to the case/switch statements in the sketch to control an output pin.

On the [website] there is the full explanation and code to build the same experience, but nothing prevent you to implement a custom way for your IR devices.

SUMO robot Arduino [Destroyer 3000]

via Arduino Blog

The user [oleglyan] is building a SUMO robot based on Arduino.

The sport “SUMO” came from Japan
which has been applied for robots.

And here is one of the categories.

The system consists of:
*A mechanical platform
*Power electronics
*Power source

Mechanical parts made of aluminum L and U profiles and sheets, all fastened with screws.
Actuators are 2 gearmotors driving 2 separate wheels with bevel gears.
In order to control these actuators, we install 2 H-bridge drivers.
And the LiPo power source around 12V to get maximum performance.
In order to be able to detect the opponent, we install 4 IR proximity sensors with range 40cm.
In order to be inside the Dohyo, we install atleast 2 line detecting sensors at the bottom of the front corners.
Arduino is a perfect solution for this project. There’s so many macros and libraries which simplifies our programming and drives directly to project realisation. With the help of it we can process all the data from sensors easily and control the system.

Nano V3.0 is a compact solution for this project.

Arduino Granary

via Arduino Blog

The example here is part of a larger project that explores the development of interactive sensory objects for and by people with learning disabilities, specifically to enhance the experience of museums and heritage sites in the UK.

In this example we embedded an Arduino Uno inside a granary loaf, together with a Phidgets 1110 touch sensor, an Adafruit Wave Shield and a portable speaker with amplifier. The sounds stored on the SD card were recorded by the participants on our project and were selected randomly each time the load was picked up.

We are not yet at the end of our first year of the project, and still finding out the many incredible things that can be achieved with an Arduino, and some basic sensors!

Thank you [kingarthursdog] that sent us this big project involving Arduino. On the [website] you can find all their projects.

Arduino Keypad for Garage Door

via Arduino Blog

Do you need to build a KeyPad for your system? [AverageGuy] did it himself. Here his story:

My old keypad GDO gave up the ghost a while back so I decided I’d undertake a new Arduino based project. I saw there were quite a number of wireless projects already and one wired, but the wired on didn’t go into any detail, so here’s an incomplete implementation. Food for thought if nothing else.

On the [website] there is a full description and the schematics. I really recommend you if you’re interested, because the explanation is complete in every aspects.
