Traffic_light

Hi, friends!
I am implementing a project about traffic light using PIC 16F877A. This is the first time I design a system, so i don't know what i have to do. Can you post a block diagram and a printed board for me to make reference? Thanks a lot!

I think you should start with tutorials.. WinPicProg Page
good luck.

This may or may not help, but Ecros Technology has a traffic light board that was a poor seller, so it's quite inexpensive. $15 for the whole kit. It doesn't come with a MCU, so your 16F877A would work fine.

What you need to do is work out a logic table using 1's and 0's you can the work out which bits you need, and you can run this through a 4 to 16 line decoder with a latch chip or a shift register or something to implement your logic.

That's the most fun part of trying to figure out your lighting pattern. I have several pages of binary code dedicated to my traffic light circuit. But once you have your pattern determined, you can start writing your code and figuring out your timing..
