Description

What it is

The 1 Channel 5V High Level Optoisolated 250V 10A Relay Module for Arduino is an electronic component that allows controlling high voltage and current circuits through a low-level signal (5V) from a microcontroller like Arduino. The optoisolation ensures the safety of the control circuit.

Features

• 1 relay channel
• Input level 5V
• Isolation voltage 250V
• Maximum current 10A
• Compatible with Arduino

What it is for

This module is useful for controlling high voltage and current devices, such as lamps, motors, or solenoids, from a low-level circuit like an Arduino. It can be used to create control circuits, security systems, or home automation.

Tutorial: How to use the 1 Channel 5V Relay

The 5V 1 channel relay is ideal for protecting your Arduino circuits from dangerous electrical currents. Useful for those working with low and high-level electrical devices.

What you need

• Arduino
• 5V Power Supply
• Connection Cable
• Electrical Component to Control

Steps

1. 1. Mount the relay on a protoboard or breadboard.
2. 2. Connect the VCC of the relay to the 5V of the Arduino.
3. 3. Connect the GND of the relay to the GND of the Arduino.
4. 4. Connect pin 5 of the relay to pin 11 of the Arduino.
5. 5. Connect pin 6 of the relay to an electrical component (e.g., light bulb).
6. 6. Connect pin 7 of the relay to GND.
7. 7. Load the Arduino code.
8. 8. Check the maximum current of the electrical component.

Example code

```
int relayPin = 11;
void setup() {
  pinMode(relayPin, OUTPUT);
}
void loop() {
  digitalWrite(relayPin, HIGH);
  delay(5000);
  digitalWrite(relayPin, LOW);
  delay(5000);
}
```
