Pinout and Usage
| Pin | Function | Connection |
|---|---|---|
| VCC | Power Supply | Connect to +5V power source |
| GND | Ground | Connect to ground |
| IN | Input | Connect to the digital output pin of your microcontroller (e.g., Arduino Digital Pin 2). A HIGH signal on this pin will trigger the relay. |
| NO | Normally Open | Connect to the load (device to be controlled) |
| NC | Normally Closed | Connect to the load when the relay is not activated |
| COM | Common | Connect to the load |
How to Use the 1 Channel Relay Module
- Wiring: Connect the module to your microcontroller and the load as per the pinout table.
- Control: To activate the relay, send a HIGH signal to the IN pin. To deactivate the relay, send a LOW signal to the IN pin.
Example (Arduino)
C++
const int relayPin = 2; // Relay IN pin connected to Arduino Digital Pin 2
void setup() {
pinMode(relayPin, OUTPUT);
}
void loop() {
digitalWrite(relayPin, HIGH); // Activate the relay
delay(1000); // Wait for 1 second
digitalWrite(relayPin, LOW); // Deactivate the relay
delay(1000); // Wait for 1 second
}
Note:
- The specific library functions and usage will vary depending on the microcontroller and the library you are using.
