I want to make a project.In traffic signals red ,yellow,and green colours are there.When red light start glowing the device(car or bike) automatically (switch off) i.e automatically stop.i want to make that project .can any one give me the circuit diagram...

 

You seem to be wishing to make a device that can spot traffic control lights with absolute accuracy. This would seem to present quite a challenge - especially at night when there are many other light sources present that would make positive identification of traffic light difficult.

When you say

When red light start glowing the device(car or bike) automatically (switch off) i.e automatically stop

that sounds like the vehicle will stop without regard for the other traffic.

Can you tell us how you are planning on dealing with these problems?

 

i just want to submit as a project in my colz .Ignore disadvantages..can u help me

 

This problem would require more than a "circuit diagram" for its solution. Correct recognition of visual cues by a machine in an uncontrolled environment is a subject for advanced research. Some people are sceptical about the degree to which this will ever be possible.

 

else when a signal is sent it will recieve by the reciever then the motor will stops.Is it possible

It is possible to make this setup in a controlled setting. Like in your school lab. But for a real world setting. Not very likely.
By the way what is "colz", and is this a school project

 

k
give me the circuit and necessary details..plzzzzzzzz

 

give me

give me
give me

gimme gimme gimme

I don't know of anyone besides the IRS for which this approach works

 

You could use a photoresistor. With correct calibration under a controlled environment, you could distinguish red and green.

I emphasise on controlled environment.

Can I contact your instructor? I'd like to get credit for my work.

Good one! Well said!
