An introduction to Arduino by Jaycar Electronics and Freetronics

Twitter: and

Last year we introduced a small range of, “Arduino,” based products, small but surprisingly powerful PCB computers and accessories. We have made some exciting additions to the range this year.

The Arduino system is very popular and easy to use for creating your own projects. Made up of a simple hardware platform and a free code editor with an easy one-click, “compile/upload,” feature, it is designed to be fast and fun without you being an expert programmer.

Free software, hundreds of examples, circuit diagrams, programs, all kinds of projects and tutorials are openly available on the Internet to support these interactive boards. Many sensors, modules and displays can be used. You can also use servo motors, DC motors, gearboxes, speakers, LEDs, switches, cases and many other electronic parts in our catalogue ( to make your project, there is no limit to compatibility with general electronic components.

This is also the most popular system for advanced users and all kinds of interactive and ambitious projects. It has been used to make robots, home automation, automotive projects, for sensing and controlling lights, motors, locks and servos, sounds and video, interactive objects like animated sculptures, toys and games, radio links and just about anything else you can dream up. It can even be a web server and connect your projects to the Internet. The software is free and cross-platform: Windows, Mac® OS X and Linux.

Many off-the-shelf plug in and prototyping, “Shields,” are available. Shields plug straight into the top of your board to extend its capabilities: motor control, radio link receivers, relay drivers, display and keypad, Ethernet, Wi-Fi, GSM mobile communication and more. Smaller, “Modules,” incorporating sensors, accelerometers, actuators, sound input and output, smart RGB LEDs and more are available to make it easy to connect interactive parts without fine soldering.

Online resources include the forum, guides and more at, the Arduino website with language reference and large worldwide forum at, and an excellent range of tutorials at Aussie local John Boxall’s

Of course Google and some of the books we stock are also an excellent resource. Keep an eye on our website or for more Arduino related products throughout the year.

    Well done 🙂

    This was really comprehensive and useful without getting bogged down in technical details. Really great for someone like myself who’s diving into Arduino for the first time.
