Relay Control Project

This project demonstrates how to control a relay module using an Arduino. The relay module allows you to control high-voltage devices like lights, fans, or other household appliances using the low-voltage digital output from the Arduino.

Features

• Control up to four relays using digital pins.
• Each relay can be turned on for a specified duration and then turned off.

Hardware Requirements

• Arduino board (e.g., Arduino Uno)
• Relay module (4-channel)
• Jumper wires
• Breadboard (optional for neat wiring)

Pin Connections

• Relay IN1 connected to Arduino pin 2
• Relay IN2 connected to Arduino pin 3
• Relay IN3 connected to Arduino pin 4
• Relay IN4 connected to Arduino pin 5

Setup Instructions

1. Hardware Setup:

   • Connect the IN1, IN2, IN3, and IN4 pins of the relay module to the corresponding digital pins on the Arduino (pins 2, 3, 4, and 5).
   • Connect the VCC and GND pins of the relay module to the 5V and GND pins on the Arduino.

2. Software Setup:

   • Open the Arduino IDE on your computer.
   • Create a new sketch and copy the provided code into the IDE.
   • Connect your Arduino board to your computer using a USB cable.
   • Select the correct board and port from the Arduino IDE.
   • Upload the sketch to the Arduino board.

Usage

Once the sketch is uploaded, the Arduino will control the relays in a sequence:

• Each relay will turn on for 1 second and then turn off for 1 second.
• This sequence will repeat indefinitely.
