In this circuit when you clap or whistle in front of a Mic, a flower connected in the output starts rotating. For making this circuit, we have used CD4013 IC, DC [[wysiwyg_imageupload::]]motor and few more components. IC CD4013 contains two independent D type flip flop which exist in one of two states and can store information. Each module is further equipped with a group of  pin outs assigned as data, set, reset, clock input and a couple of complementary outputs Q and . As we know, it has couple of output that change or toggle state as response to trigger applied to input terminals.  To put in simple words, this circuit describes movement of a DC motor based on the voice sensing capabilities provided to it through a microphone. The DC motor can be accessorized using a variety of attachments such a miniature flower (in this case), a small fan etc.
