help with arduino choice of controller

Projects General Guidance
1

hello guys,

i am planning to build a traffic light with a motion sensor so it will help regulate traffic. Basically, my idea is when there are no cars around the light will turn green and go back to working normally. Any idea to which of these boards works the best to be working with a timer such as regular traffic lights. I am new with arduino boards as well as the software. Any suggestions will help as to why i should use that particular board, will be very much appreciated. Looking forward to earin from you. Thanks.

What "Other Software Development" activity is this related to? This should be in Project Guidance, since that is what you are looking for.

Any board has enough pins to read a motion sensor and turn a light off or on.

Any board knows how long it has been running, which is all the "timer" you need.

Traffic lights, in the US at least, do not use motion sensors to detect the presence of vehicles.
