hello, i want to control traffic light signals through M68hc11 .the approach is ,when a car come, the signal will turn on otherwise turn off.i want to know the code of this program .if any one know let me aware too . thax tanveer haider |

Why do you need a controller to do this? A loop detector on the road which triggers a timer that keeps the light on for a certain length of time will do the trick. A traffic controllers is a very complicated bit of equipment which has to have a lot of fail safe measures and doesn't just turn lights on and off. REMEMBER people WILL DIE if the controller misbehaves. Also a commercial type of controllers will need more than just a HC11. Perhaps you should tell us a bit more about you project.

> Why do you need a controller to do this? IME, the only people who ever ask this FAQ are students with a project. Just ignore them and let them do their own study, or you'll help foist yet more witless "engineers" on the world. |

Regards John Samperi helo John, i am a student .i have an assignment of M68hc11 .it is to use m68hc11 microcontroller and write code for traffic light control system(in mini ide).i have to complete it in one week.My teacher allow me to use net for this purpose.i visit various sites but didn't find desired knowledge.so i leave my question here.Because the basic purpose is to get code and study it for further enhancement. thank u tanveer haider ****************************************************** Ampertronics Pty.
