Portable traffic light / Wan Mohd Ehsan Wan Md Nor and Mohamed Safiyan Mohamed Ali

This Project is inspired by the situation incurred by pedestrians, which for the most part are students who need a crossway in order to obtain public transportation or to get to the campus; the difficulties that are faced by the personnel to exit the parking lot as well as the students who nave a vehicle and to help those lecturer to go anywhere without distribution at road way.
This device was built and tested during a month to obtain figures and demonstrate benefits reported.
The device should be low maintenance, it should have a long lifetime and, be simple enough to be operated by those who use it. Among the benefits found, the safety of the students, the prevention of accidents such as car crashes and run over.
This project operates red, amber and green LEDs in the correct sequence for a single UK traffic light.
The time taken for the complete red - red & amber - green - amber sequence can be varied from about 7s to about 2% minutes by adjusting the IM preset. Some amber LEDs emit1 light that is almost red so you may prefer to use a yellow LED. The 555 astable circuit provides clock pulses for the 4017 counter which has ten outputs (Q0 to Q9).
