Arduino: Making a set of traffic lights

Step 9 And they all lived happily ever after... The End.

Your done!

Through out the code I have written comments and you can read these to find out what each line does, and then try tinkering with it to see what happens, at worst case you can just restore it back to the original.

However if you need more help or guidance I have a few links and resources below...

Before I go I would like to thank Alex and the team at Tinker.it who taught me all I know on one of their Beginners workshops, they are truly brilliant at what they do, thank you!!! Also thanks to Sparkfun.com and Rapidonline.com who are an amazing resource of parts for arduino!

Ok so editing the sequence for the R,Y,G for the U.S. is easy... The question I have is, do you really need the buzzer in there? Is it at all possible to remove the buzzer and add a resistor that is the same value as the buzzer in place of that? I guess I am going to have to build this... Although I am thinking of making it on a larger scale. and doing 4 sides to it. and having 4 cross walk signs too... Thanks for the basic idea...

Could you not just edit the code so it doesnt have a beep command rather than putting in a resistor?
