How To Interface Relay With Arduino

A Relay is an electromagnetically operated switch. Relays are used to control a circuit. Many relays consist a coil, a yoke, and an armature. When a current is passed through the coil, a magnetic field is induced in the coil which moves the armature and relay start its switching function. A normal relay has NO(normally open), NC(normally connected), COM and coil pin within it. A Simple one channel relay is shown in below image Relay Required Components For designing a relay driver circuit...
