Red Yellow Green (a) PE 16-2 TrafficLight Part 2 1. Automate the stoplight from PE16-1 so that it changes color automatically after an appropriate amount of time. (i.e. cycles like a real stoplight) 2. Replace the color buttons with a "start" and "stop" button to control the light.
I need part 2 put into this code!!!
