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

Build an interactive coin donation box with Arduino

Many community groups, hackerspaces, charity events and financially-strict households may have a donation or coin box to collect funds for drinks, fines or generally help save up those small coins - however they can often be quite dull.

To liven things up somewhat, Saiyam Agrawal has created a coin box with some fun interactivity - once a coin is inserted, a thank you sign is waved at the user which hopefully emits a feeling of goodwill and satisfaction.

Making your own is easy - with an ultrasonic distance sensor to detect the user, and a servo to wave after donation. Control is via Arduino and the whole project can be made in an hour or two. Check out the video below for a quick demonstration:

So if you're looking to liven up your money box or donation tin - click here to get started.

Make a desktop laser engraver with Arduino

Have you ever seen a laser-cutter machine or CNC (Computer-Numerical Control) machine and thought "wow, I'd like one of those"? Well now you can make your own based around an Arduino or compatible hardware and the notes by Instructables member MichielD99.

They describe a desktop laser-engraver that not only introduces you the theory and control of a CNC device - you can also make it yourself as the enclosure is made from wood and all the parts are easily obtainable. This example uses a 1.8W laser however you could substitute a more powerful version if required.

The pattern to be engraved is created or imported into open-source software Inkscape, and then converted to a grbl file for upload to the Arduino or compatible controller.

With some research you could make your own over a weekend - so visit the Instructable page to get started. And for more, we're on facebookGoogle+, and twitter - so follow us for news and product updates as well.

If you're looking to develop projects based on an Arduino that use stepper motor, CNC machines on a larger scale, and much more - simplify the process with our Freetronics StepDuino board:

The StepDuino is a complete, self-contained Arduino-compatible board with 2 onboard stepper motor drivers, 2 servo outputs, a 20x4 LCD, a micro SD card slot, and more! It's a fantastic general purpose board for any project that uses stepper motors. You can use it as the brain of your next robotics project!

The StepDuino uses the same processor architecture as the common Arduino Uno, so you can program it right from the Arduino IDE simply by selecting "Arduino Uno" as the board type. Everything simply works out of the box, just as it would with a regular Arduino - but now you can also drive steppers directly and display feedback on the huge LCD. For more infromation, tutorials and to order - visit the StepDuino page.

Make an Arduino-controlled Syringe Pump

Home scientists and others who could use an accurate syringe pump will know that a commercial unit can be quite expensive, and thus out of reach. However with some time and effort you can make your own version based around Arduino and compatible circuitry and a 3D printer.

Instructables member isotope32 has demonstrated how this can be possible, and the results are quite successful. An Arduino can easily control a stepper motor, and with this in mind the controls can be customised to suit your own purposes - including your own user interface.

All the part files and other details have been provided, so visit the project Instructable page to get started. And for more, we're on twitter, facebook and Google+, so follow us for news and product updates as well.

Experimenting with data capture using Raspberry Pi and Microsoft Azure

There are a plethora of cloud-based services that can be used to receive and analyse data, and the following example uses Microsoft's Azure to receive data from a Raspberry Pi. In order to demonstrate this, Instructables user cgaine has two DS18B20 temperature sensors that are connected to a Raspberry Pi which captures the data and sens it to Azure.

Both hardware and software sides are explained, including the python code for the Pi, using the Azure API and also setting up the Azure database and event hub.

For complete details on this interesting application - 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 interested in measuring temperature with a reliable sensor - consider using our DS18B20-based temperature sensor module:

The Freetronics temperature sensor modiule uses the Dallas DS18B20 1-wire digital temperature sensor, with a wide measurement range of -55 to +125°C at an accuracy of +/- 0.5°C. For more information, tutorials and to order - visit the product page

Make your own classic "Breakout" video game with Arduino

Making your own video games may seem difficult, however nothing could be further than the truth. And your Arduino or compatible board has enough processing power to run a wide variety of classic video games that are quite enjoyable - so why not make your own?

A great example of doing so has been documented by Samarth Artweaver who built his own Arduino-compatible on protoboard, which uses the simple yet effective TVout library for monochrome composite video output in order to play "Breakout". This offers a real 1970s-style gameplay as showin in the video below:

Although this is quite simple, it shows that can you can generate reasonable video for gaming or information from your Arduino. For all the information and sketches required to make your own, visit the project 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, such as the Breakout game described above - you'll need a protoshield to mount the external circuitry. When doing so, consider our range of ProtoShields. From the tiny LeoStick to the Mega we have a wide range to suit your application.

Experimenting with electronics? Build the Companion IC

One of the great features of the Arduino development platform is that you can make your own test equipment without too much effort, and the following project by Srijal Poojari is an excellent example of what is possible.

His "Companion IC" offers not only a neat desktop clock, but also offers an ohmmeter, capacitance meter, diode tester and could also be expanded for other uses. Not only is this easy to reproduce, Srijal also explains the theory and concepts behind the measurement functions which makes interesting reading as well. A demonstration is showin in the following video:

Tracking the true cost of meetings with Arduino

Returning to the office after the holiday period may find some of our readers stuck in meetings of incredulous lengths, and more often than not you'd rather be getting on with the job instead of dealing with a talkfest. Robert Korn had the same issues and has come up with a creative and fun solution - the Arduino-based meeting cost display.

This unit displays the increasing cost of his time using an LCD - so the longer the meeting, the more it will cost his employer. This could also be used on your desk - when approached by people you'd rather not talk to, start the timer and show them that time is money! Building your own is simple - just add an LCD keypad shield to a Freetronics Eleven or compatible and you're set.
