I'm trying to design a circuit for my local rc car club. I wanted to build a drag racing christmas tree. Intially I wanted the pre-stage lights to light when a button is depressed, starting the 1 miunte count down. At 20 seconds to start the staging lights would light up. Then at 4 seconds to start, the 3 yellow lights would count down sequencially 3 seconds and the green light would finally light up, starting the race. Any ideas on how to do this?
I was thinking of building a basic digtal clock that would count from 59 to 0 using divide-by-10 and a divide-by6 chips. When the 20 mark came around the 2 digit would start the staging lights and so forth. Make any sence, or am i totally off on this one?
