gothrough the project by vlivking this link. the ckt n its ecplanation abt workin is givin, i hav understood tht, no problem till tht, however practically speakin , in a traffic system of cross lanes , one display shows red , yellow green in a particular sequence for a certain time, while the other display of red green n yellow does with the same sequence but with a different time, as in wen one diplay shows red the other shows green, for cross lanes
so wat all do i need to do to add another three leds , tht show red while the prior shows green
take notice of the pulse allotments by the 4017 ic to each led while suggesting ur plans,
each n every idea is welcome , thank u
