Traffic light design

Hello guys, plz i need to know the arduino to use for the design of traffic light system to be put in front of a school with a pedestrian control for crossing.

Traffic lights are a project that we often see here. A search of the forum or Google for "arduino traffic lights" should get lots of information on hardware and code.

Hi,
Arduino UNO or THIS: derivative UNO compatible with added 5V current and easy-to-connect pins might be good...
