Using Analog Comparator in PIC Microcontroller

Comparator Module in PIC Analog Comparator is a device which compares two voltage signals and switches its output to indicate which one is larger. The analog comparator is used in many applications such as battery charger, analog to digital converters, IR sensors where we need to compare two signals. Most of the PIC Microcontrollers have built in Comparator Module which makes ease of design and saves cost. For demonstration, we use PIC16F877A. PIC16F877A consists of two analog comparators which can be used in eight different...
