Arduino Relay Module Tutorial Roland Pelayo Arduino Tutorial 1 Comment 8,596 Views A relay is commonly used to interface a low-current circuit to a higher-current circuit. IN1 – Controls relay 1, active Low! This relay module contains two 5-volt SPDT 10-amp relays, optoisolators, status LEDs, clamping diodes, and transistors to drive the coils. We use a breadboard to connect the VCC and Ground to both modules from our UNO, but we connect a 1N4007 rectifier Diode to the VCC line of the Relay Module to allow the current to go only one way. We connect the IR Motion sensor “OUT” to Pin 4 and the Relay “IN1″ to Pin 8. One important thing that is sometime forgotten is to use a Rectifier Diode when switching High Voltage. I bet unless you really use them, you may always be thinking of knocking them all out before using them in your project. But because the Arduino operates at 5 volts, it cannot directly control these higher voltage devices. As mentioned earlier, by interfacing Arduino with 5V relay module, we intend to operate an AC load like lamp. Software¶ Step 1. Introducing the Relay Module A relay is an electrically operated switch that can be turned on or off, letting the current go through or not, and can be controlled with low voltages, like the 5V provided by the Arduino pins. This is possible with the use of relays. I'm, Patrick Norton., I'm, Michael Hand.. We were going to bring you the most amazing confluence of alumin Description: In this Arduino project, I have shown how to use Lora with Arduino for different IoT projects. It has a standard interface that can be controlled directly by microcontroller. Since we are using LINE VOLTAGE of 120V, you should take the necessary precautions when dealing with high voltage.
