Arduino 5v Relay Module Circuit Diagram

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.

Arduino 5v relay module circuit diagram. Now we need to test the circuit diagram of the relay module on a breadboard. A relay is an electrically operated switch that you can use to control mains voltage appliances. Circuit diagram and working. So connect the 5v and the ground of the arduino with the 5v and the ground of the 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. Here we have used 6v relay module. Commonly used in iot projects to control lights and other electronic appliances. 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.

The connections for connecting the relay module with arduino are very simple. A simple project in which arduino uno controls a 5v relay is explained here. 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.

In this arduino relay control circuit we have used arduino to control the relay. Circuit diagram and explanation. 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. 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.

Below given is relay driver circuit to build your own relay module. Now we have all the parts to make a diy relay module. This instructable is for connecting your arduino to a 2 channel relay module and using your sketch to control the switches i bought the 2 relay module on ebay for 9 50 to drive a couple of 240v parts a vacuum cleaner and a rotary engraving tool. 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.

In this example we will connect the relay module with arduino in the normally open state. Don t skip this step it is necessary to avoid mistakes when soldering into a pcb and check if it is works. There is no connection between the low voltage circuit operated by the microcontroller and the high power circuit. To power the relay module you need to supply 5v in the vin pin of the relay board.

Arduino 2 channel relay. This post shows how to use a relay module with an arduino board. The working of the project is based on the functioning of the relay and the ability of arduino to control the relay.
