Im having some trouble on how to make a certain counter circuit light up an LED just like an ordinary traffic light ??? ::). for example. i want the green led to light up for 5secs then turns off.. then, the yellow led for 2 secs.. then the red led for 10 secs and so on.. the cycle repeats itself.. i dont prefer the usage of a microcontroller or something to do with programming the IC.. i would like to do this by the use of resistors and other ordinary components.. tnx for your replies... ;D
