Although many people enjoy controlling motors, robots and sensing data with an Arduino, you can also have some fun - and one simple to create idea is making music. This has been demonstrated by Joe Marshall and Instructables user "Joe Marshall" who have worked together to make an eight-tone synthesiser (thus the use of the word "Octophonic"). The electronics side is rather easy, as the Arduino can do all of the work - and with the use of copper-plated fibreglass boards as "keys", the interface is quite neat and user-friendly- for example:
It's also great to see some effort made to create a suitable enclosure. The Arduino sketch incorporates some straight C code however it's documented well - so check out the project page for more information. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
When making your own circuitry for an Arduino-based project such as the solar cell tester mentioned above, 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 range, we offer a complete range for you to work with.
