Time to check out another entry in the Freetronics Instructables competition, a fantastic example of a Gainclone audio amplifier unit by Instructables member andrew_h. Although the Gainclone amplifier itself isn't the focus of the project, the use of an Arduino to create a user-interface and control system for the amplifier is very well done.
By using three parts which are controlled via the i2C bus, the onboard Arduino compatible makes it easy to control volume, bass, treble, switch inputs, an FM radio, and also have a real-time display as shown in the following video:
It's great to see enthusiasts are bringing home-made audio gear into the 21st century, so to find out how - visit the project Instructable page. And for more, we're on facebook, Google+, and twitter - so follow us for news and product updates as well.
Have you been reading about Arduino and would like to understand more so you can work with projects like the example above, but not sure where to start? Then order one of 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.
