Clap control led Brightness Controller…
Controlling of led lights using regular switch is older today. So in this project we will see you, How we can make a clap control Led Brightness controller .
By using this circuit we can control the brightness of any led light.
The circuit can be modify according to our need also we can control any DC fan speed by using this project.
As the project named “clap control” so there must be a part of sound. So the heart of this project is the “Mic
Condensor” . As we know microphone receive the sound & turn it into an electrical signal. So when we input a sound, the mic condensor will produce an electrical signal,which will trigger the 4017 decade counter IC.
In 4017 decade counter we will use 4 outputs.So at first signal the led will on at full brightness. On 2nd signal the brightness will decrease one step. On 3rd input the brightness will be minimum & on 4th signal the led will be off & the process will continue.
Now if anyone wants to upgrade this into 6 steps or even 8 steps then we just modify this circuit.
Now come to the led part, we have to use a power transistor to drive our led, because the 4017 ic will not be able to deliver such amount of current to the led.

Order the Components :
In this project I use LCSC.COM
“Lcsc.com” one of the largest Electronics Components provider around the world.
Here are some best thing about LCSC.COM
A lot of components available
Price is very cheap
4$ off at first order
Very good packaging for every components with details
A lot of company available
