Controlling Fan With IR Remote Using Arduino Mega 2560

Introduction

• In this article you will learn about how to control Fan with IR Remote using Arduino Mega 2560.
• We can control the fan by using the remote in our place if we want to control the fan by the remote. 

Parts Of Lists

• Arduino mega 2560
• IR Remote
• Servo Motor
• Bread Board
• Hook Up wires 

Connection

Step 1

Connect the IR Remote to the Arduino Mega 2560

• Connect the IR Sensor to the arduino board Vin -3pin,
• Connect the IR Sensor to the arduino board Gnd - Gnd.
• Connect the IR Sensor to the arduino board Vcc - 5v.  

Step 2

Connect the ServoMotor To the Arduino Mega 2560

• Connect the Vcc of the servo Motor to the 5v of the ArduinoMega2560.
• Connect the gnd of the bluetooth to the Gnd of the ArduinoMega2560.
• Connect the Vin of the bluetooth to the 09 of the ArduinoMega2560.

Programming

#include <IRremote.h>      //must copy IRremote library to arduino libraries
#include <Servo.h>
#define plus 0xA3C8EDDB   //clockwise rotation button
#define minus 0xF076C13B  //counter clockwise rotation button

int RECV_PIN = 3;       //IR receiver pin
Servo servo;
int val;                //rotation angle
bool cwRotation, ccwRotation;  //the states of rotation

IRrecv irrecv(RECV_PIN);

decode_results results;

void setup()
{
  Serial.begin(9600);
  irrecv.enableIRIn(); // Start the receiver
  servo.attach(9);     //servo pin
}

void loop()
{
  if (irrecv.decode(&results)) {
    Serial.println(results.value, HEX);
    irrecv.resume(); // Receive the next value

    if (results.value == plus)
    {
      cwRotation = !cwRotation;      //toggle the rotation value
      ccwRotation = false;         //no rotation in this direction
    }

    if (results.value == minus)
    {
      ccwRotation = !ccwRotation;   //toggle the rotation value
      cwRotation = false;            //no rotation in this direction
    }
  }
  if (cwRotation && (val != 175))  {
    val++;                         //for colockwise button
  }
  if (ccwRotation && (val != 0))  {
    val--;                         //for counter colockwise button
  }
  servo.write(val);
  delay(20);          //General speed
}

Explanation

• In this article I explained about the Contolling the fan by using IR remote.
• It can contol the speed of ON/OFF and this is can be made by the Arduino Mega 2560.
