Hello,
On the pages of the EDUCYPEDIA you will find a lot of subjects:

Just pick a subject of your interest and start reading / building.

I would have used Google. It is a lot projects out on the net. The quality may vary. But feel free to post any question here. It is more easy to help on specific questions.
Also then you post always include your schematic. Then we will be able to help you much faster.

hi
one idea in my mind is to design a circuit for traffic light,which can measure intensity of traffic also..
how the circuit can sense the intensity of traffic?

Hello,
The amount of traffics can be measured with loop in the road.
When a car passes you can detect the car using the loop.
You can feedback the loop information to a microcontroller, that can take the desission wich way should have a green light for a smooth traffic handling.

but here is restriction to use microcontroller
do any one have another idea?
plz suggest..

Hello,
A quick search on this forum here gave this page with some circuits to create a traffic light:

It does not look at the amount of traffic.

Counting traffic is easy.
Set a timer for a minute.
Use a button to represent a signal from a car detector loop.
Count the number of button presses in on minute.
Now, you can wait ten minutes, and average the numbers.
So you now can figure, if you have a red light for 1min 30sec, how many cars will be lined up,stopped.
If the number of cars is too high, for instance if the street can only hold 22 cars before they are in the previous intersections, you want to be sure the light changes back to green before 22 cars are stopped.
Adjust the time of the cycle depending on the number of cars per minute.

what is car detecting loop?
A loop of wire that is put into the ground at stop lights.
It is basically a metal detector.
When an automobile drives over the loop, the control "knows".
It produces a signal when a car is present.
Ever been in downtown Philadelphia gridlock?
Let's see, no new presses, I guess the light should stay red. Or, make them all green. Same outcome.

Most in-the-road metal detectors do not properly control the flow of traffic.
I think a clock is used instead but it is set to a weekend when the actual day is a working day. On a Saturday or Sunday the traffic light blocks everybody but allows "nobody" to turn for a long time. Then on a working day nobody can turn and nobody can go anywhere.
