Exercise 2:
Let us consider the table below representing the sequences of a junction light. Only the diodes
lighting are representing in the table.
Sequence 1 Green 1 Red 2 Red 3
Sequence 2 Yellow 1 Red 2 Red 3
Sequence 3 Red 1 Green 2 Red 3
Sequence 4 Red 1 Yellow 1 Red 3
Sequence 5 Red 1 Red 2 Green 3
Sequence 6 Red 1 Red 2 Yellow 3
The junction traffic light is represented as follow:
a) Suggest an electronic circuit able to manage that project, using a PIC18F452 microcontroller.
b) Write al algorithm for the program
c) Write a program in an environment of your choice (Proton Basic or MiKro C), for PIC18F452.
