can i use a 7-segment display to show the time remaining for the signal to change??....if yes then how??<br>
are u willing to use a microcontroller or not?
You can do it with a 7447 and a 7490(TTL gates and not a microcontroller) THERE ARE SITES WITH SCHEMATICS TO DO THIS!!!
no not a microcontroller.....
year this is a great circuit also posted at http://www.kpsec.freeuk.com/projects/trafficlight.htm<br>thanks for making an instructable about it as it was hard to read
yellow should always be before red light
u r correct but now i have to redesign the circuit
justswitch the red and green LEDs
it's purpose is to get ready!...by the way nice project rohit!..
