Arduino Relay Module Circuit Diagram. In the transmitter lora circuit we have connected the transmitter lora module with arduino nano as per the circuit diagram. I have explained this smart relay module circuit in the tutorial video of this home automation project.
The electromagnet requires a small voltage to get activated which we will give from the arduino and once it is activated it will pull the contact to make the high voltage circuit. A relay is basically a switch which is operated by an electromagnet. This is the complete circuit diagram for this smart home automation project.
A relay is basically a switch which is operated electrically by electromagnet.
In the transmitter lora circuit 5 push buttons are connected with arduino digital pin d2 d3 d4 d5 d6 whenever we press any push button the signal sent to receiving the lora module to turn on or off the respective relay. A relay is basically a switch which is operated by an electromagnet. An ac bulb is used for demonstration. A relay is basically a switch which is operated electrically by electromagnet.
