    I have to make a logic curcuit and a model of an intersection as a school project.
    I would like some advice like which PIC would you recommend and software to build the curcuit in. I was thinking about Alpha, but I'm afraid that it doesn't have enough inputs/outputs.

    I must have 4 traffic lights for vehicles and 4 for pedestrians (it doesn't have to be on both sides for pedestrians).

    http://youtu.be/OzMYf2dIfms this is how the model should look like

    Thank you for any info you can give me :)

    The 18F4321(a little older) is a popular PIC for schools to use. It is a 40-pin device, but there are many out there that will work.

    Multiplexing could drastically reduce your I/O requirements.
