Today I’m going to show you how to control any device with an Infrared remote(TV,DVD,AC etc.) and with the help of Arduino board. So lets get started.

Things you’ll need :-

Infrared receiver (I’m using one from the TSOP 17** series)
Arduino board.
Breadboard.
Couple of jumpers/single stranded wires.
A LED Any remote(AC, TV, DVD player).

Connections :-

Of Infrared reciever-
Pin 1 – GND (Ground pin of Arduino).
Pin 2/Middle pin – VCC (5v supply of Arduino).
Pin 3 – Data pin (pin number 3 on Arduino).

Note :- The pin no. 3 is a bit separated from the other two ! Don’t misunderstand between pin1 & pin3 !

Procedure :-

First things first, make the connections.
Now to turn ON/OFF any LED with the help of any remote we must know the value/code of the button through which we are going to change the state !
Download the IRemote library online from this link. Copy & paste the code I’ve provided. Upload it.
After uploading, click on the Serial Moniter option in the top right corner of Arduino window.
Press the buttons you wish to control your LED with. Note down the values which appear in the Serial monitor window.
Making changes in your code by replacing YOUR values with “YOUR VALUE 1” & “YOUR VALUE 2” in the code.
Again upload the code & test it out !

Code :-

#include <IRremote.h>
 
int RECV_PIN = 3;               //declared for receiving pulses
int c=0;                        // declared if you want to control with a single button
IRrecv irrecv(RECV_PIN);
decode_results results;


void setup()
{
   pinMode(9, OUTPUT);
   Serial.begin(9600);
  irrecv.enableIRIn();                      // Start the receiver
}

void loop() {
  if (irrecv.decode(&results)) {
    Serial.println(results.value);
    irrecv.resume();                        // Receive the next value
  if(results.value==YOUR VALUE1)                                       
  {
             digitalWrite(9,HIGH);
  }
  else if(results.value==YOUR VALUE2)
  {
             digitalWrite(9,LOW);
  }
                                }
}


/* if((results.value== YOUR VALUE3)&&(c%2==1))                    // enables you to turn on & off with the help of same button"                  
  {
                digitalWrite(9,HIGH);
  }
  else if((results.value==YOUR VALUE3)&&(c%2==0))
  {
                digitalWrite(9,LOW);
  }
  c++;
 }}*/

#include <IRremote.h>

int RECV_PIN = 3; //declared for receiving pulses

int c=0; // declared if you want to control with a single button

IRrecv irrecv(RECV_PIN);

decode_results results;

void setup()

{

pinMode(9, OUTPUT);

Serial.begin(9600);

irrecv.enableIRIn(); // Start the receiver

}

void loop() {

if (irrecv.decode(&results)) {

Serial.println(results.value);

irrecv.resume(); // Receive the next value

if(results.value==YOUR VALUE1)

{

digitalWrite(9,HIGH);

}

else if(results.value==YOUR VALUE2)

{

digitalWrite(9,LOW);

}

/* if((results.value== YOUR VALUE3)&&(c%2==1)) // enables you to turn on & off with the help of same button"

{

digitalWrite(9,HIGH);

}

else if((results.value==YOUR VALUE3)&&(c%2==0))

{

digitalWrite(9,LOW);

}

c++;

}}*/

Here’s a video tutorial which will definitely make things easier for you 😉

Please comment below if you face any difficulties. I’d love to solve them 🙂 .

Cubli :-

A combination of two words, Cube – an English word & li- an Swiss German diminutive word meaning ”small”. Researchers from the ETH Zurich’s Institute for Dynamic Systems and Control have developed the Cubli, a 15x15x15 cm device that can walk, jump, and balance itself on its edge or even on a corner.

Researchers said that balancing was not a big issue for The Cubli, while the problem was jumping up from the rest position because at that instant, it needed more energy so they used reaction wheels mounted on three faces of the cube which rotated at high angular velocities & then brake suddenly which caused cubli to jump.

Once the cube stood up on a corner, controlled motor torques were applied to balance on one point.
In addition to balancing, motor torques were also used for a controlled fall in any direction.
Combining these things – jumping up, balancing, and controlled falling — the Cubli is able to walk on its own !
