Component Name

5V 1 Channel Relay Module (Made in India - GL Make)

Description

The 5V 1 Channel Relay Module is a widely used Internet of Things (IoT) component designed to control high-power devices using a low-power signal. This module is manufactured in India by GL Make, a reputable electronics manufacturing company. It is a single-channel relay module, meaning it can control one device at a time.

Example 1: Controlling a 220V AC Light Bulb using Arduino
In this example, we will use the 5V 1 Channel Relay Module to control a 220V AC light bulb using an Arduino Uno board.
Hardware Requirements:
5V 1 Channel Relay Module
 Arduino Uno board
 220V AC light bulb
 Breadboard and jumper wires
Software Code:
```c
const int relayPin = 2; // Pin connected to IN pin of relay module
void setup() {
  pinMode(relayPin, OUTPUT);
}
void loop() {
  digitalWrite(relayPin, HIGH); // Turn on the light bulb
  delay(1000);
  digitalWrite(relayPin, LOW); // Turn off the light bulb
  delay(1000);
}
```
Explanation:
In this example, we connect the IN pin of the relay module to digital pin 2 of the Arduino Uno board. We then use the `digitalWrite()` function to send a HIGH signal to the relay module, which closes the NO and COM contacts, allowing the 220V AC light bulb to turn on. Conversely, when we send a LOW signal, the relay module opens, and the light bulb turns off.
Example 2: Controlling a 12V DC Fan using Raspberry Pi
In this example, we will use the 5V 1 Channel Relay Module to control a 12V DC fan using a Raspberry Pi.
Hardware Requirements:
5V 1 Channel Relay Module
 Raspberry Pi
 12V DC fan
 Breadboard and jumper wires
 12V power supply
Software Code:
```python
import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BCM)
relay_pin = 17
GPIO.setup(relay_pin, GPIO.OUT)
while True:
    GPIO.output(relay_pin, GPIO.HIGH) # Turn on the fan
    time.sleep(1)
    GPIO.output(relay_pin, GPIO.LOW) # Turn off the fan
    time.sleep(1)
```
Explanation:
In this example, we connect the IN pin of the relay module to GPIO pin 17 of the Raspberry Pi. We then use the `GPIO.output()` function to send a HIGH signal to the relay module, which closes the NO and COM contacts, allowing the 12V DC fan to turn on. Conversely, when we send a LOW signal, the relay module opens, and the fan turns off.
These examples demonstrate the basic operation of the 5V 1 Channel Relay Module and its ability to control high-voltage devices using a low-voltage signal. This module is an excellent addition to any IoT project requiring relay control.
