Arduino 5v relay circuit.

Carries the trigger signal from the arduino that activates the relay. The only link is by the magnetic field. Whenever we need to connect any ac appliance in our embedded circuits we use a relay. The second version is an actual relay board that i have at home and analyzed the circuit.

If you used a 12v relay like we used in this project arduino relay control you need to use a separate power supply for relay. In this example we will connect the relay module with arduino in the normally open state. The connections for connecting the relay module with arduino are very simple. The detail instruction code wiring diagram video tutorial line by line code explanation are provided to help you quickly get started with arduino.

Learn how to use relay with arduino how relay works how to connect relay to arduino how to code for relay how to program arduino step by step. The first version is a recommendation that i found on the internet. 5v or 6v relay. It can be turned on or off allowing the current through the circuit.

The relay module has three low voltage terminals i e vcc gnd and signal. Here we are not using any relay driver ic like uln2003 and will only use an npn transistor to control relay. Coming to the design of the circuit it is very simple as we used a 5v relay module and not the individual components. So in this arduino relay control tutorial we will simply learn how to interface a relay with arduino.

Inside the relay is a 120 240v switch that s connected to an electromagnet. A relay accomplishes this by using the 5v outputted from an arduino pin to energize the electromagnet which in turn closes an internal physical switch to turn on or off a higher power circuit. Connects the arduino s 5v pin. So connect the 5v and the ground of the arduino with the 5v and the ground of the relay module.

This makes it easy as arduino can power up the relay directly. A relay is basically an electrical switch that is operated by an electromagnetic switch. 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. This circuit is for a 5v relay to be attached to an arduino nano.

Circuit diagram and explanation. When the relay receives a high signal at the signal pin the electromagnet becomes charged and moves the contacts of the switch open or closed.
