Arduino 5v Relay Schematic. Because the relay can handle up to 250v it will be able to control power to any 240v device in the house from lights to audio equipment. It may be simpler and more obtainable to use the arduino to control a relay that controls another relay.
Three on one side and three on other side on the bottom side there are three pins which are signal 5v and ground. The working of the project is based on the functioning of the relay and the ability of arduino to control the relay. A relay is an electrically operated switch that can be turned on or off letting the current go through or not and can be controlled with low voltages like the 5v provided by the arduino pins.
Let us discuss the working of the project.
Circuit diagram for relay with arduino code for relay with arduino the working of the above sketch is as when the ldr senses darkness i e. Three on one side and three on other side on the bottom side there are three pins which are signal 5v and ground. Moving on from components and pinout here is the circuit diagram of the dual channel relay module. Since the arduino operates at 5v it can t control these higher voltage devices directly but you can use a 5v relay to switch the 120 240v current and use the arduino to control the relay.
