Arduino Relay Control Tutorial with Code and Circuit Diagram In this arduino relay control tutorial we will simply learn How to interface a Relay with Arduino. Here we are not using any Relay Driver IC like ULN2003 and will only use an NPN transistor to control relay. What is an Electrical Relay? (with pictures) An electrical relay is a switch that is under the control of another circuit. A classic example is the system used to start a car — when someone turns an ignition key, the ignition does not interact directly with the car battery.Instead, it activates a relay, which passes the signal on so that the car can start. Electrical Codes for Junction Boxes Ask The Electrician NEC 314.16 Wiring Methods Junction Box Fill The volume of electrical boxes shall be sufficient for the number of conductors, devices, and cable clamps contained within the box. Code Adoption Information: The codes shown are examples only and may not be current or accurate for your application or jurisdiction. HS Code for connectors for electrical cables Heading 8536. Electrical apparatus for switching or protecting electrical circuits, or for making connections to or in electrical circuits (for example, switches, relays, fuses, surge suppressors, plugs, sockets, lamp holders and other connectors, junction boxes), for a voltage not exceeding 1|000|V; connectors for optical fibres, optical fibre bundles or cables Wiring Electrical Control Relays A relay contactor is a large relay, usually used to switch current to an electric motor or other high power load.
