It must be the week for floppy-drive music projects as we have another one by Simon Schoar which is both functional and very easy to use. Based on the Atmel AVR platform, the jukebox can read MIDI files from an SD card, and with a neat user interface the user can select and play files with ease. The drives are controlled using a serial data bus, each with their own custom controller PCB - and for further effect RGB LEDs are fitted inside the drive for some blinking to the music, for example:
Again, another imaginative project that's a lot of fun. Plus all the required code, schematics and design files have been published so you can learn more or even make your own. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
If you're looking to make more creative designs with LEDs, consider the Freetronics RGBLED: full colour module. It includes a bright RGB LED on the top of the board and a WS2801 constant-current, addressable, multi-channel LED driver on the back. This smart module can be daisy-chained, so you can connect a number of these together in a string and drive each of the module colours individually from your microcontroller.
