Question

((This is MicroController Question, it's about PIC18F452))

Modify the program to perform the following algorithm:
a) Configure the following 5 pins as outputs (for o/p devices)
RC0 (RELay 1) RE0 (RELay 2) RC2 (Cooler=fan) RC5 (Heater) RC1 (Buzzer)
b) Switch OFF all these 5 devices if portD reading: (75 < PORTD < 150)
c) Switch ON only Heater and REL2 if (PORTD < 75).
d) Switch ON only Cooler and REL1 if (PORTD > 150).
e) Switch ON also the Buzzer if (PORTD > 220)
