Sir,
5V realy not avelable in my local market.
Can i use 6V realy in that place?
If , it is not possible. Please harry e-mail me what i do in that case. Please please harry. . .

You can use a 6V relay in place of 5V relay, but your power supply should be 6V

100nF is not avelable in my local market.
Please suggest me, what can i do?

sir, can we use 12v relay instead of 9v relay by 9v battery power supply ?

Hi…. i have did a clap switch which is somehow different from the above circuit. I use a comparator and a differentiator as a replacement for the 555 timer and the usage of RC delay circuit. An NMOS acts as a switch to light up the LED when the RC discharge is above the threshold voltage. The LED will light up for sometime until RC discharged is decayed to below the forward voltage of the LED.
The question here is: without the use of a relay, how do i stop the light from fading when my first clap occur and how do i off the LED when my second clap occur? Please kindly advice.

If you know CD4017 or CD4027, you can use it to latch without using relay. Try a D-flip flop or this circuit: http://new.electronicsforu.com/newelectronics/circuitarchives/view_article.asp?sno=298&title=&id=265&article_type=1
In this project remove IR sensor and add the electret mic circuit and try it once. When you clap, the circuit triggers at pin2 and CD4027 latches.

sir this project is awsom…
i have a doubt.. what is the role of capacitor c3 of BASIC CLAP SWITCH…

i want to know what is the specification of this electret microphone?
In brazil i didn´t find nothing that works equal…
thanks

Sir,
I made clap switch using IC555, but its flip-flop switch,means when clap just LED lid and off again within a second, while I want to use this circuit with toy car so my purpose not solve. I got this circuit from http://www.minibread.org/wp-content/uploads/2012/04/basic-clap-switch.jpg.
what modification I do, plz send circuit diagram.

is it okay if your transistor is so hot and smells bad?

hello sir,
can u please upload the circuit connecting video for this circuit plzzzzzzzzzzzzzzzzzzz as u have done for simple clap circuit……………
and can we use normal bread board instead of the mini bread board
plz donot forget to upload this circuit being connected by u neatly as previous one ……………

i just tried this circuit its working fine but i want to use it for my room light , so there is a problem its not sensing my clap from distance i have go very near to do it .
give a solution soon,
eagerly waiting

sir i make the circuit but mine just light even without the condensor mic and this condensor mic heats very fast and i cant even touch it as if the timer ic didnt recognize amplified signal from the mic……wat shall i do sir i even had check my biasing and its correct….

Hey i really loved the design and style. Thought the one
thing had been really cool.

This is a thing that everyone should do. It’s a faster and also easy
option to keep things straight forward.

why do we have two LED’S in the clap switch with monostable circuit

I AM TRYING TO MAKE A CLAP ON AND OFF SWITCH WITH ONLY ONE IC i.e. A NE555 TIMER. CAN YOU SUGGEST SOME GOOD CIRCUIT DIAGRAM TO MY MAIL AND I AM FINDING SOME DIFFICULTIES IN GETTING A BD139 TRANSISTOR . CAN YOU NAME ANY OTHER TRANSISTOR THAT CAN SUBSTITUTE THIS BD139. AN EARLY REPLY IN EXPECTED FROM YOUR SIDE . THANK YOU
