Interfacing Relay with PIC Microcontroller

Understanding the Role and Function of Relays in Electrical Circuits

A relay is an electromagnetic switch which is used to switch High Voltage/Current using Low power circuits. Relay isolates low power circuits from high power circuits. It is activated by energizing a coil wounded on a soft iron core. The Role and Function of Relays include controlling the flow of electricity between circuits, providing electrical
