How to make Traffic signal autonomous model project for kids.
Do it your self project.

Hello Friends,
In this video we are going to see how to make Traffic signal autonomous project for kids.
This is totally autonomous project and it will run automatically in continuous loop.
Two types of signals are present, first one is Traffic signal with three color lights and another one is pedestrian signal with two color lights.
Traffic signal is for wheicals and another is for pedestrian humans.

Project: Pedestrian signal is RED (stop), Car/Bus will start from start position and Traffic Signal will be green, Bus will move forward and traffic signal will change to Yellow then Red,
Bus will get stop at zebra crossing, Pedestrian signal will change to green (WALK), old man will cross the road.
After some time Pedestrian signal will change to RED (stop) and Traffic signal will change to Green,
Car/Bus will star again towards school. It will get stop at school and signal will be change to Yellow then RED.
Old man will cross road again. After that Car/Bus will come back to origin position at start. And It will continue again in loop automatically.

Working: I have attached 3 Reed sensor bottom of road one is at starting position, 2nd is at Zebra crossing, 3rd is at End near school.
one Optical/Speed sensor is connected near Stepper motor which is used to detect old man position when project getting powered up.
3 Aluminum foil coated strips/pips are attached on road, two of them are carrying 5V DV supply to drive Car/Bus and they are connected to DC motor diver.
One Magnet is connected under Car/Bus so that reed sensor will able to detect Car/Bus position.
This all things are controlled by Arduino Nano micro controller.
