The people behind the GreatScott! YouTube channel have published another fun project that is easy to make and offers great results. This example is an LED colour organ, which uses the MSGEQ7 graphic equaliser IC to determine the various levels from music or sound.
These are passed to an Arduino which controls high-powered LEDs via MOSFETS - which in this case are mounted in used bottles and look great when illuminated. Apart from the final results, the build process is shown in the following video:
This would look great behind a bar or along the wall at night when music is being enjoyed. For all the technical details, download the project file (.rar). And for more, we're on facebook, Google+, and twitter - so follow us for news and product updates as well.
If you're making a similar project and need to control large currents with your Arduino digital outputs - you'll need a MOSFET. We've got you covered with out NDRIVE: N-MOSFET driver/output module:
This high-power N-MOSFET module lets you switch high-current loads using a tiny microcontroller. Perfect for controlling that set of traffic lights mounted in your living room! Works brilliantly for automotive projects such as switching high-power 12V lights and high wattage LEDs. For more information and to order, visit the product page.
