Freetronics: Arduino-Compatible Electronics Kits & Parts

Here at Freetronics we design, sell and support our range of flexible, easy to use boards and modules, making it easy for you to build your own electronic projects.

What Is Arduino? Arduino is a very popular and easy to use programmable board for creating your own projects. Consisting of a simple hardware platform and a free source code editor with an easy “one-click compile/upload” feature, it’s designed to be really easy to use without being an expert programmer. Arduino is also the most popular microcontroller board for advanced users and all kinds of more ambitious projects.... Read more

Now we really are back!

The domain renewal finally went through on Monday so everything is running smoothly again.

Thanks for your patience!

We're back ... almost

I'm back in the office and busy shipping out orders, but we've had a major problem: while I was away over the last few days our ".com" domain expired!

Unfortunately that domain was registered by someone who left Freetronics a few years ago, so I didn't receive any warnings that it was going to expire and I haven't been able to renew it. Luckily our site has been running on the "" version of our domain so it's still accessible, but problems include:

  • We're not receiving any support email
  • Product / documentation URLs printed on some product packages and PCBs don't work
  • The forum URL doesn't work
  • Order confirmation emails and shipping notification emails came from an email address that couldn't receive replies
  • Our direct email addresses don't work

To work around this I've transitioned as much as I can over to the domain, so if anything doesn't work, just add ".au" into the address. That goes for the forum, email, documentation, etc:

I'm really sorry about this inconvenience. Hopefully we'll have the .com domain back soon.

Freetronics shipping closed until June 21

Over the next few days Freetronics will be closed, with shipping to resume around Wednesday next week.

If you're super quick, orders placed in the next couple of hours may ship out today. Otherwise they will have to wait until next week.

Skill Sunday: Interfacing Arduino with MATLAB

MATLAB is a very popular tool often used by engineers for technical computing, data visualization, simulation and algorithm development. What many people don’t know is that it is possible to connect an Arduino compatible board to MATLAB. This can be achieved through the MATLAB Support Package for Arduino which allows MATLAB to communicate to the Arduino through the USB cable. Not only does this give you to power to blink LEDs from MATLAB, but you can also configure your Arduino to easily collect data and send it into the MATLAB environment where it can be processed using the full power of your PC. Using the MATLAB environment it is also possible to create graphical interfaces to control hardware attached to your Arduino board, and much more! If you want to learn more about how this can be done there are many tutorials available including this one from from All About Circuits or this video series from Mathworks (the creators of MATLAB).  


Have you been reading about Arduino and would like to understand more? Checkout our Experimenter's Kit for Arduino:

Experimenter's Kit

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. The kit also includes a great project and instruction booklet, plus access to a supporting web page and software examples. To get started or for more information and to order, checkout the product page.

Skill Sunday: Speeding Up Your Code

Arduino is a very easy to use platform and comes with many pre existing functions that make it a great learning tool. However, this does come at a cost. One of the costs that comes with this simplicity is that many of the functions can actually be quite slow. You might not notice this when you are flashing a single LED, however once your projects become more and more complicated and tight timing is required, you may start to notice that commands such as digitalWrite may not be as quick as you require. Fortunately it is not too hard to program your Arduino in “true c” which gives you far greater control and can increase the speed of turning on and off a digital input (and other functionality) by as much as 10x! To find out more checkout this instructable from RazorConcepts.

If you are looking for an Arduino board why not check out the Freetronics “Eleven” Arduino Compatible Board.  


The Eleven is just like an Arduino Uno (and 100% compatible), however the Freetronics team have made a number of improvements to the Arduino Uno design such as adding in a prototyping area, using a micro-USB connector and many more. These improvements mean that the Eleven is as easy to use as possible and is of the highest quality! To find out more about the fantastic Freetronics Eleven check out the following link. The Eleven has just come back into stock, so order soon to avoid missing out!
