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).
Portable traffic light very simple product which is can give many effort and benefits to ours as specially to people in uitm Dungun . Among the benefits found we have the safety of the students, and the prevention of accidents such as car crashes and runs-over. |
