i need your help badly..
i need a pcb layout for a four way traffic light.. i cant find any..

what are you gonna using? I mean what is the features of your traffic light? is it the same as what we seen at the street

 

[mitch214]

we'll be using parallel port interfacing..
kinda hard for me 2 search for a circuit board lay-out..
uhm.. yah.. same with those on the street..

Hi Mitch,

here is a circuit published by Colin Mitchell (talkingcircuits - 50 555 circuits).

It uses a timer and a decimal counter.

It's not quite realistic, since the phase from red to green is normally indicated by the red and yellow light simultaneously.

If you can live with that fact just use it.

You want to control it with a computer? What kind of lights will you use?
