Exercise #2 -- Traffic Control using 6 Lights Modify your program so that the 3 lights which represent the other traffic direction are also controlled. It is tempting to use six timers for this task, but the job can be done with just four, and you'll end up with a much cleaner program as a bonus. Red = O:2/00 Green = O:2/02 Amber = O:2/01 Green = O:2/06 Amber = O:2/05 Red = O:2/04 8 Sec. 4 Sec. 8 Sec. 4 Sec. < Time in Seconds > Still getting the odd Crash? Well it's pretty obvious that these drivers aren't paying much attention to Amber Lights! No need for any more wiring however. You can solve this problem, but it's going take a little more programming.
