Setting Up the Relay Module

Integrating the 2 Channel Relay Module with an Arduino is straightforward. Here’s a simple guide to get started:

1. Connections:
   • Connect the VCC pin of the relay module to the 5V pin on the Arduino.
   • Connect the GND pin of the relay module to the GND on the Arduino.
   • Connect the IN1 to IN8 pins to digital pins on the Arduino (e.g., pins 2 to 9).
2. Wiring the Load:
   • Connect one terminal of each appliance to the common (COM) terminal of the respective relay.
   • Connect the normally open (NO) terminal of each relay to the power source.
   • The other terminal of each appliance should be connected to ground.
3. Programming the Arduino: Here’s an example code to control the relays:
   cpp

   Copy code

   int relayPins[] = {2, 3, 4, 5, 6, 7, 8, 9}; // Define pins for the relays

   void setup() {
   for (int i = 0; i < 8; i++) {
   pinMode(relayPins[i], OUTPUT); // Set relay pins as outputs
   }
   }

   void loop() {
for (int i = 0; i < 8; i++) {
digitalWrite(relayPins[i], HIGH); // Activate relay
delay(1000); // Wait for a second
digitalWrite(relayPins[i], LOW); // Deactivate relay
delay(1000); // Wait for a second
}
}
