Arduino 5v Relay Module Circuit Diagram

5v isolation relay module description the isolation relay module is an electrically operated switch that allows you to turn on or off a circuit using voltage and or current much higher than a microcontroller could handle.

Arduino 5v relay module circuit diagram. Don t skip this step it is necessary to avoid mistakes when soldering into a pcb and check if it is works. A relay is an electrically operated switch that you can use to control mains voltage appliances. In this arduino relay control circuit we have used arduino to control the relay. Now we have all the parts to make a diy relay module.

Circuit diagram and explanation. Circuit diagram and working. 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.

How to set up a 5v relay on the arduino circuit basics working module for mc easyeda pinout description datasheet simple switch diagram 2 channel wiki tutorial control high voltage devices with ky 019 steps2make code and how to set up a 5v relay on the arduino circuit basics working 5v relay module for mc easyeda 5v relay read more. 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. To control the relay you. Below given is relay driver circuit to build your own relay module.

This post shows how to use a relay module with an arduino board. So connect the 5v and the ground of the arduino with the 5v and the ground of the relay module. There is no connection between the low voltage circuit operated by the microcontroller and the high power circuit. In this example we will connect the relay module with arduino in the normally open state.

As mentioned earlier by interfacing arduino with 5v relay module we intend to operate an ac load like lamp. Now we need to test the circuit diagram of the relay module on a breadboard. Here we have used 6v 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 power the relay module you need to supply 5v in the vin pin of the relay board. 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. Assemble all the parts as shown in the schematic diagram. Arduino 2 channel relay.

Commonly used in iot projects to control lights and other electronic appliances. The connections for connecting the relay module with arduino are very simple. 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.
