I made the 555 timer circuit. At first I was having the same issue as some others as in the LED was on from the start. Instead of changing out the resistor each and every time, I put a 200k variable resistor in place and found the best level that way. Then replaced with a normal resistor. Many thanks for sharing, much appreciated. You have earned my subscription.👍🇬🇧😷
Can share a picture of ur circuit I'm having the same issue
@@thatfnafguy8242 me too
WORKINGGGGGGG FINALLYYYY
Bro my led turn ON only continuously doesn't goes off
The led is continuously glows why?Give any solution for 2nd circuit using transistor
Sir pls tell how time the led glow when i use 100uf capeciter
It's working I did this circuit...
Mine are not work can you please help me
The led is On before I connect the mic, but when I connect it, the circuit doesn't work
Why is that happening?
I too faced the same issue
Can anyone help .
What is the type of microphone ?
Sir, could you pls send me working notes of this project pls
As soon as i connect the LED glows continuously, doesnt go off
Sir, pls send working notes
Led is getting ON directly from supply....not responding to claps or sounds...what may be the prblm?? And how can we fix it out ?
Try changing 47k resistor with 100k resistor...'worked for me'and keep the circuit away from direct sound from fan or anything because it seems to be very sensitive circuit
BRO CAN YOU HELP ME TO MAKE
Sir not working led isn't off
Does it works whit the BC548
Yes, it works with any n-p-n transistor.
My circuit is not working. The only change I did is using 220 ohm resistor instead of 330 ohm
Changing 330 ohm to 220 ohm does not create any problem, you should try increasing the other capacitor values.
Very very very thanks. Wow it really worked but it does.not work when I clap but it works.when I beat my bed. Any solution?
You are very luck it works
I've created it on dotted PCB but it's not working only the led is is glowing which can be done from direct supply also . Where I am getting problem plz tell me
The circuit might be extra-sensitive, you can try:
1. Increasing resistance values, or
2. Keeping the circuit away from direct air like from fan or so.
Is the capacitor necessary?
yes
i'm having the same problem. the led is constantaly on by direct supply..the mic is not responding to clap..
The circuit must be extra-sensitive, try:
1. Increasing resistance values, or
2. Keeping the circuit away from direct air like from fan or so.
@@Molted yes i increased the resistance.i used 100k instead of 47k .now it's working..thanks for the help..
I don't have bc 547 , I have bc548
the transistor switch did not work for me. Only works for some people NOT me. My bc547 must be different. My 1 meg resistor must be wrong? My 10k must be wrong. Is this a scam??? I have made lots BUT none work. WHAT TYPE OF BC547 ARE YOU USING. iS IT SOMETHING DIFFERENT? This is a waste of time.
Please help
not a thorough circuit
