The circuit uses the CMOS dual D type flip flop CD4013 which contains two positive-edge triggered flip flop to toggle a load connected through a relay. Now [[wysiwyg_imageupload::]]with the help of a switch you can on the device once pressing it and off the device again using the same switch. In CD4013 each module is further equipped with a group of pin outs assigned as data, set, reset, clock input and a couple complementary output Q and Q(not) . As we know it has couple of output that change or toggle state as response to trigger applied to input terminals. In this circuit, one is wired in toggle mode while other is not used. Using this circuit we can easily control AC and DC appliances remotely through inexpensive low voltage cable and a standard push to on switch. This circuit can easily support a cable length of 25 meters.
CD 4013 Based Two Way Switch
In festival days, we switch ON the lights of our corridor, balconies or staircase. In the case when people have lighting done at two different locations, they have [[wysiwyg_imageupload::]]to go to two different places to switch ON the light but, with the help of this circuit, you can switch ON both the lights with a simple touch. This simple circuit is built around CD4013 which has two independent flip flops on a single chip and each module is further equipped with a group of pin outs assigned as data, set, reset, clock input and a couple complementary output Q and NOT Q. CD4013 is a 14 pin IC which contains two independent sets of flip flops and in our circuit we are utilizing both. Read on more to find out how the circuit is made and how it works.
Flip Flop based Staircase Switch
In many cases, the stairs have a power switch at the bottom which is often left switched on during night. No one wants to go down to switch it off and hence, [[wysiwyg_imageupload::]]unnecessary on, it leads to wastage of electricity.To solve this problem we have described a simple circuit which contains two micro switches; one at the top and other located at the bottom of the staircase that can be pushed and released easily during climb-up from the bottom of the staircase or climb-down from the top of staircase. In short you can use any switch to on and off the light.This simple circuit is built around a CD4013 IC which has two independent D type flip flops which exist in complimentary 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 complementary output Q and Not Q.
CD 4013 based Sound Sensing Module
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.
