Hello everyone,
Firstly, i agree, i am a newbie and dont do much about circuits
I need some help urgently please,
i need a circuit to run a dc motor for 5 seconds when received signal from ir sensor , and stops after 5 seconds , and doesnot starts until second signal received

please reply soon i need the circuit urgently

THANKS IN ADVANCE

 

If it is so urgent that you need to post the thread twice and put Urgent!!! in the trhead title, why don´t you go on the internet and find someone who will do it ASAP for you, of course for some nice sum of money?

 

actually i have to use this in a science project and give it a home made look
without any proffessional
can u please provide me a circuit diagram
ir should be the simplest

 

As a rule, we don't respond to urgent requests, unless it is something like

"my fingers are stuck in the CD bay and can't get them out!!!"

or

"URGENT: my wife is about to toss my computer out the window, I need someone to catch it!!!"

This reminds me the days...when I was still a *student* and always in panic mode...
From your first post we can tell that you haven't done any researches whatsoever...but sounds like a nice little project!

Gudluck! (that's what people like to say!)

 

Motor voltage? Motor current? LM555 monostable!

This is not urgent care!

 

Look up (on this site) circuits using the 555 timer IC. The one you want is called a "one shot" or a monostable multivibrator.

 

Helllo,

I merged the threads and moved the new thread to the momework section, as it is a project.
I deleted the excess in posts.

can you please provide me simple circuit diagram with proper requirements?
i would be very thankful


all other mates,it is seriously urgent

 

Here you are http://lmgtfy.com/?q=555+monostable
Is so hard to use some goddamned search engine? I remember the times when people were really grateful that something like a search engine even existed, today people are too lazy to use it by themselves and need to ask others to do it for them...

 

kubeek - that was AWESOME !!! I will have to google that myself - I have folks asking me about stuff all the time and they could just do what I did - google it !!!! I loved the animated google search............

 

being ur junior, thanx for reply

i got the idea for monostable timer 2 days ago, but couldnt find any way to trigger it with ir sensor for 1 second and run motor for 5 seconds, please please help dont tease me
its request to u and urgent

 

What are the motor specifications? Voltage and Current.

What sensor are you using to "trigger" the event that requires the motor to run for 1 second?

This is your homework. If you want me to provide a solution, I need the answers to the questions and your professor's email address. After all, you seem like you have minimum interest in doing your homework.

it's a small toy car motor with 1.5 to 4.5V DC

most probably i will be using IR sensor (like a Beam cut Sensor), which when blocked for 1 second, gives trigger to the motor to run for 5 seconds


ABout Home work: it's not my homework, even i am not doing any electrical study, it's just a hobby assignment to show someone special coming today evening

thnx

 

Ive got the solution!

LEARN BASIC ELETRONICS!

Nothing is for free.

How old are you? 12?

 

Here ya' go ... you provide a pulse of 5V and the output will go high for 5.5 seconds

You got my only. Freebie for the year.
