Experimenting with ATmega328 microcontrollers and 3D graphics

In a fascinating demonstration of what you can do with limited computing resources, Themis Benetatos has demonstrated several methods of defining and displaying three-dimensional objects with an Arduino or compatible board and a small TFT LCD display.

Themis runs though a few proof-of-concepts for tiny 3D engines, and gives some interesting comparisons. Furthermore code to convert .STL files to text to insert into .h header files is provided so you can experiment with your own graphics using his code. Some examples of the progress of the 3D engine are shown in the following video:

Apart from the enjoyment of creating your own 3D animation, there is lots to be learned with respect to describing 3D models in code and dealing with memory limitations - so to get started visit Themis' interesting website. And for more, we're on facebook, twitter and Google+, so follow us for news and product updates as well.

If you're looking for a neat and colourful display to use with your Arduino or Raspberry Pi - consider our 128x128 pixel OLED Module. With a diagonal size of 1.5" and 16,384 colours to select from, so almost anything is possible. Furthermore there's a microSD card socket, and removable tabs on each side which can hold LEDs and buttons:

And using the module is made simple - we have tutorials and drivers for both the Arduino and Raspberry Pi platforms - great for experimenters or those who use both systems. Furthermore, check out the forum where members are already creating modified drivers to rapidly increase the display speed. For more information including our Quickstart guides - and of course to order - visit the OLED Module product page.

Create Arduino games to be played with a dog

And now for something completely different - video games that were designed to be played with a dog. Well not by a dog alone, however the controls are large enough in that a small dog could be trained or coaxed to jump onto the controls when required.

This process has been documented by Michelle Westerlaken who created very large buttons for her Arduino by using a sandwich method that consists of two layers of foil with sponge in between, a clever and simple solution to making buttons that are durable and also withstand pressure by the dog.

From there the Arduino is used as a game controller and can be used with example games in processing, or by using a Leonardo-compatible the system can emulate a USB keyboard. Check out the following video for a fun demonstration:

For complete details, visit Michelle's Instructable page. And for more, we're on twitter, facebook and Google+, so follow us for news and product updates as well. 

If you found the project above interesting - but not sure how to start with Arduino, then the best way to learn is with our Experimenter's Kit for Arduino:

The package includes a wide variety of parts, sensors and modules including: a servo motor, lights, buttons, switches, sound, sensors, breadboard, wires and more. Furthermore a Freetronics Eleven Arduino-compatible board is included to make this an extensive hobby experimenter, inventor and starter kit. However we don't leave you alone to figure it all out, included is a great project and instruction booklet, plus access to a supporting web page and software examples. In other words - this is everything you need to get started for a fun range of electronics and Arduino related projects! So to get started or for more information and to order, check out the product page.

Create a unique "Hand-in-hand" Arduino-powered clock

We can never get enough interesting clock projects, and this latest example by Instructables member dragonator is a great example of what can be done with some imagination and a 3D printer.

They have created an analogue clock that, quite simply, has the minutes hand extended from the tip of the hours hand - which is also the centre of rotation for the minutes. Watch the video below for an accelerated demonstration:

The clock itself involves an Arduino-controlled stepper motor which turns the hours hand, and a series of gears inside the hours hand which then turn the minutes hand. Ingenious. And thanks to the creator open-sourcing the entire project, you can make one too. To get started, visit the clock's Instructable page. And for more, we're on facebook, twitter and Google+, so follow us for news and product updates as well.

Looking for a small Arduino-compatible board to embed into final projects? Consider our LeoStick - it's the Arduino Leonardo-compatible board that's cheaper and smaller than the original:

Apart from being one of the smallest Arduino-compatibles on the market with USB, it also has an onboard RGB LED and piezo which can be used a knock sensor and various tune and sound effects. Plus you can add extra circuitry with the matching protostick! For more information and to order, click here.

Moving time-lapse photography made easy with a Raspberry Pi

Time-lapse photography is a simple and fun way to record the activity of a particular area over time, and is useful for monitoring plant growth, movement of people and objects, creating art and just having fun. However a new dimension to the exposures can be created if the camera can also move small small distances between exposures along a particular axis - and thus moving time-lapse is created.

One excellent example of a moving time-lapse device has been documented by Instructables member telonics who shows us to use a camera-equipped Raspberry Pi and move it along a rope with a stepper motor. The software on the Pi can determine the exposure length, period between exposures and shuttle itself along the line when requried. Then it's up to the end user to combine the images into a short movie with video editing software - that can result with interesting output such as the video below:

Furthermore the project continues by mounting the device on a small model railway wagon, with the track on an incline and the stepper motor winding the device up or down the slope by collecting or releasing a thin line. A truly fascinating device which you can recreate yourself, so to start visit the project's Instructable page. And for more, we're on facebookGoogle+, and twitter - so follow us for news and product updates as well.

If you're looking for a neat way to add external circuitry to your Raspberry Pi model A+, B+ or 2 model B then check out our new PiBreak Plus Raspberry Pi Prototyping Board:

This is a great way to add your own electronic components, circuitry, sensors or other devices to your Raspberry Pi model A+, B+ or 2 Model B - any of the current Raspberry Pis with a 40 pin GPIO header. The PiBreak Plus also includes a GPIO female header to solder yourself, and a pair of nuts, bolts, washers and spacers to ensure a a great fit.

And in the Freetronics fashion we've used a quality gold-plated (ENIG) PCB for durability, brought out all the power rails along with the GPIO next to the prototyping area to make adding circuits a breeze. Furthermore the pinouts are labelled on both the top and bottom of the PCB to save time referencing the right GPIO pins. For more information and to order - visit the PiBreak plus page now!

Make your own Arduino-powered Centrifuge

As more people become interested in science, testing and chemistry in general - there becomes a need to access more complex equipment for various tasks, however this can often be outside the reach of many people who need one. However with some time and effort, various devices can be made and one example is this neat centrifuge by Instructables member orlov127.

For the uninitiated, a centrifuge is "... a machine with a rapidly rotating container that applies centrifugal force to its contents, typically to separate fluids of different densities (e.g., cream from milk) or liquids from solids" (thanks Wikipedia), and basically a device that can spin a test tube or two around at a very high speed - and with this example at around 30,000 RPM.

This home-made unit uses an Arduino to control a repurposed Dremel hand tool, which provides the hardware to rotate at such a high speed. A 3D printer is used to create the tube holder, and the enclosure is laser-cut for neatness. The Arduino can be used to control the speed and also duration of each session.

This is a great example of what can be made with some time and imagination, so visit the project Instructable page to learn how. And for more, we're on twitter, facebook and Google+, so follow us for news and product updates as well. 

 If you are new to Arduino and looking to make your own centrifuge, join in with our range of Arduino-compatible hardwareprototyping shields and module range. A great start is the Freetronics Eleven, the Arduino Uno-compatible board with onboard prototyping space:

Build an Arduino-powered Rubik's Cube game

As part of a university course, David Sharfi and fellow group members were tasked with creating an electronic device, and resulted with a great example of an electronics "Rubik's Cube" game. This involves a large number of LEDs all driven by the Arduino via shift registers, which sounds complex but with some planning is quite simple.

By using nine LEDs on each face of the cube the state of play can easily be understood, and buttons on all faces of the cube are used to "move" the cube's pieces in either axis. Check out the following video for a demonstration:

This is an incredibly imaginative and interesting project, and along with the Arduino sketch David's group have also provided the schematic and details required to make the PCBs to reproduce your own game. For more information visit the project's Instructable page. And for more, we're on facebook, twitter and Google+, so follow us for news and product updates as well.

If you're interested in this project, or building your own RGB LED cube - check out our 4x4x4 RGB LED Cube Kit:


It's easy to construct and use, and with an onboard Arduino-compatible board the cube can be used to display all sorts of data or create visual effects. It's easily controlled via simple text commands via the USB port - or write your own Arduino sketch. It's incredibly customisable and there's so much more.

Build an inexpensive Spirometer with Arduino

We never cease to be amazed at the range of interesting test equipment you can make with an Arduino, and another great example has been documented by Instructables member MariaL7 who shows us how to make a Spirometer. For the uninitated, this is a device to measure the volume of air that passes through a tube or cylinder which has a fixed diameter.

The Spirometer uses a Honeywell differential pressure sensor, which in itself is an interesting device that measures the difference in air pressure between two areas, and uses this data to calculate the air flow. Then with some maths which have been explained in the tutorial, the volume of air flowing through the tube can be determined and displayed with an inexpensive LCD shield:

You can learn more about this interesting project from the Instructable page. And for more, we're on facebookGoogle+, and twitter - so follow us for news and product updates as well.

If you need to add external hardware or devices to your next Arduino project, you'll need a protoshield to mount the external circuitry. In doing so, consider our range of ProtoShields. From the tiny LeoStick to the Mega we have a wide range to suit your application.
