The Singing Ukelele is created using a broken Ukelele, an Arduino, a Wave Shield from Ladyada.net, LDR’s and other various circuitry.
An SD card holds the mp3′s and are changeable so that you can programme the LDR’s to play.. well anything. The Ukulele can be played stand-alone or plugged into an amp via guitar pedals to go crazy with possible sounds.
