Arduino 5v Relay Module Circuit Diagram

A relay is an electrically operated switch that you can use to control mains voltage appliances.

Arduino 5v relay module circuit diagram. Whenever the hall effect sensor is subjected to a magnetic field it toggles the relay as per the code. Here we have used 6v relay module. Now we need to test the circuit diagram of the relay module on a breadboard. 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.

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. The working of this circuit is very simple. Below given is relay driver circuit to build your own relay module. The working of the project is based on the functioning of the relay and the ability of arduino to control the relay.

To control the relay you. A simple project in which arduino uno controls a 5v relay is explained here. Let us discuss the working of the project. The arduino can be programmed to turn on the relay when a certain event occurs for example when the temperature of a thermistor gets higher than 30 c.

Don t skip this step it is necessary to avoid mistakes when soldering into a pcb and check if it is works. This post shows how to use a relay module with an arduino board. 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. Commonly used in iot projects to control lights and other electronic appliances.

As mentioned earlier by interfacing arduino with 5v relay module we intend to operate an ac load like lamp. To power the relay module you need to supply 5v in the vin pin of the relay board. The circuit diagram for controlling a 5v relay module with hall effect sensor and arduino is shown below. So connect the 5v and the ground of the arduino with the 5v and the ground of the relay module.

Assemble all the parts as shown in the schematic diagram. 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. A relay is basically a switch which is operated electrically by electromagnet.

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. The connections for connecting the relay module with arduino are very simple. Circuit diagram and working. 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.

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 explanation.
