Hello yasir_66,

Please stop scattering your posts.
You have already posted in several threads about the same problem.
This is confusing for the people who are trying to help you.
Here are the other threads, one even closed by hgmjr.

Please post a photo of your counter and the complete schematic here
(including the optocoupler you are talking about).

Greetings,
Bertus

 

hello bertus this is the photo of my counter.
i dont scatter threads actually i am new user there4 i am unfamiliar from scattering posts.
thnx bertus

 

Hello,

Is the motor powered from the same powersupply?
Use some capacitors of >10 uF and 0.1 uF on the power connections of the motor.

Greetings,
Bertus

PS use the most left button to reply, the one on the right of it will start a new thread.

 

Along with Bertus' suggestion of the caps across the motor's supply, use a diode in reverse (cathode towards +v) connected across the motor. This will help to eliminate the reverse-EMF spikes when the brushes break contact.

 

YES motor is connected to same supply & for controlling speed i used 5k(502) potentiometer.

 

Just a 5k(502) pot? Or does the pot control a 555 timer to provide PWM control to the motor?

 

there are two pots
1 is of 100k pot which is for increasing decreasing frequency of 555 & another pot is of 5k which is for controlling motor's revolution.

 

Hello,

Do you have the schematic of the complete setup?
So the counter, the NE555, the optocoupler, the motor and potmeter connections.

Greetings,
Bertus

 

ok ill make schematic on paper then ill send u snap & i used insulated wires(used in transformer's winding) in this circuit so does it effect? or leakage resistance producing by it?

(meaning post an image of the schematic)
Do you know that you can download certain schematic capture programs and use them as freeware? Cadsoft Eagle is one that you can use to make not only schematics, but small circuit boards as well. Google will tell you where to download it.

I used insulated wires(used in transformer's winding) in this circuit so does it effect? or leakage resistance producing by it?

That is fine for the CMOS part, as long as you scraped/burned off the insulation where you needed to solder it.

Oh, and instead of an "optocoupler", you have a "photointerruptor", or "OPTICAL INTERRUPTER SWITCH". Fairchild makes a similar looking device with a part number of H21A1; you can find it's datasheet searching for that part number.

Bertus and I were trying to tell you to connect capacitors and a diode across the motor's connection, like this:

 

ok sgtwookie ill connect cap & diode.
& yes that is photointerruptor i made mistake.
you mean insulated wire is good choice for CMOS?
can i use these insulated in future with CMOS?

Your salvaged transformer wire will work fine with small projects like this. CMOS IC's don't require much current. It looks like the salvaged transformer wire is rather small gauge. It would probably have too much resistance for high current circuits.

 

hello sgtwookie,
i want to make a simple audio amplifier plz help me for making it.Do u have any schematic for this?

 

sgtwookie electret microphone has polarity?
how can i analyze anode & cathode of electret microphone?

 

You should start a new topic for the new project, otherwise things will get confused.
Here is a topic to help you understand electret mics:

Did you get the problem with the current project resolved?

 

no Sir i m still suffering but no problem just touching problem occuring remaining working good.

 

Did you add the capacitors and diode across the motor as has been mentioned?

 

yes i did but same problem still occuring.

 

Hello,

You say you are using an optocoupler.
Can you post a COMPLETE schematic?

Bertus
