Arduino 5v Relay Module Circuit Diagram

The working of the project is based on the functioning of the relay and the ability of arduino to control the relay.

Arduino 5v relay module circuit diagram.

After all parts you collected lets go ahead to the next step. As mentioned earlier by interfacing arduino with 5v relay module we intend to operate an ac load like lamp. Circuit diagram and explanation. Below given is relay driver circuit to build your own relay module.

The connections for connecting the relay module with arduino are very simple. Now we have all the parts to make a diy relay module. In this arduino relay control circuit we have used arduino to control the relay. 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.

Circuit diagram and working. In this example we will connect the relay module with arduino in the normally open state. Whenever the hall effect sensor is subjected to a magnetic field it toggles the relay as per the code. Light intensity below 500 then the relay module gets input from arduino through pin 9 and there is a connection between the com and no pin is established and turns on the light.

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. A relay is basically a switch which is operated electrically by electromagnet. Now we need to test the circuit diagram of the relay module on a breadboard. The circuit diagram for controlling a 5v relay module with hall effect sensor and arduino is shown below.

Let us discuss the working of the project. So connect the 5v and the ground of the arduino with the 5v and the ground of the relay module. Here we have used 6v relay module. Arduino ky 019 relay module is used to control ac circuits the relay acts as a switch that responds to a signal received from the arduino it has an integrated led that indicates if the signal is high or low.

A relay can be used to control high voltage electronic devices such as motors and as well as low voltage electronic devices such as a light. The working of this circuit is very simple. To power the relay module you need to supply 5v in the vin pin of the relay board. Don t skip this step it is necessary to avoid mistakes when soldering into a pcb and check if it is works.

Commonly used in iot projects to control lights and other electronic appliances. A relay is an electrically operated switch that you can use to control mains voltage appliances. Relay module for arduino is one of the most powerful application for arduino as it can be used to control both a c and d c devices by simply controlling the relay by giving 5v. A simple project in which arduino uno controls a 5v relay is explained here.

Here to turn on the relay with arduino we just need to make that arduino pin high a0 in our case where relay module is connected. This post shows how to use a relay module with an arduino board.
