For this project we had to make traffic lights and a program that makes the lights run. We had to use green, yellow and red L.E.D lights. First we made a power source, Then we added the buffer. Next, we added the three L.E.D lights and resistors. We also made a program which makes the lights go in correct sequence with appropriate delays. We connected a parallel port wire to the buffer and then the buffer sends the sequence to the lights. Then we had to make a report to say what we did. This project used mostly all of what we had learned the whole year to make.
