Interfacing a Relay with PIC Microcontroller – MikroC
A relay is an electromagnetic switch which is used to switch High Voltage/Current using Low power circuits. Relays isolate as well low power circuits from high power circuits, this is a good feature especially for safety reasons a section of the circuit with high dangerous voltage/current could be isolated from the user. When a low voltage is applied to the relay (coil wounded on a soft iron core), this coil becomes a magnet which in turns energizes the soft...
