Overview

The 12V 1 Channel Relay Module (10Amp) is a versatile and widely used IoT component that allows you to control high-power devices, such as lights, motors, and appliances, using a low-power signal from a microcontroller or other IoT device. This module features a single relay channel with a maximum switching current of 10A and a voltage rating of 12V.

Pinout

The module has the following pins:

VCC: 12V power supply
 GND: Ground
 IN: Input signal (typically from a microcontroller)
 NO (Normally Open): Relay output pin
 NC (Normally Closed): Relay output pin
 COM (Common): Relay output pin

How it Works

The relay module works by using a low-power signal from the IN pin to control the high-power relay. When the IN pin is set high (typically 5V), the relay is energized, and the COM pin is connected to the NO pin. When the IN pin is set low (0V), the relay is de-energized, and the COM pin is connected to the NC pin.

Code Examples

### Example 1: Controlling a Light Bulb with Arduino

This example demonstrates how to use the 12V 1 Channel Relay Module to control a light bulb using an Arduino board.
```cpp
const int relayPin = 2; // Pin 2 is connected to the IN pin of the relay module

void setup() {
  pinMode(relayPin, OUTPUT);
}

void loop() {
  digitalWrite(relayPin, HIGH); // Turn the light bulb ON
  delay(1000);
  digitalWrite(relayPin, LOW); // Turn the light bulb OFF
  delay(1000);
}
```

while True:
    GPIO.output(relay_pin, GPIO.HIGH) # Turn the motor ON
    time.sleep(1)
    GPIO.output(relay_pin, GPIO.LOW) # Turn the motor OFF
    time.sleep(1)
```
