ARDUINO based IR remote control robot

                      

Hi everyone. This my new project IR remote control robot using arduino. This is a simple design robot you can easily build it.

Project requirements:

•   Arduino uno
•   Tsop1738 (ir receiver)
•   H bridge ic (L293D)
•   Two dc motor
•    A robot base
•    9v Battery

For The circuit diagram refer the bellow device pin description and make connection to arduino based on the program of the robot:

Important: connect ir receiver out to arduino digital pin 11 only.

•     Connect arduino pin 7- l293d IN 1 pin 2
•     Connect arduino pin 6- l293d IN 2 pin 7
•     Connect arduino pin 5- l293d IN 3 pin 11
•     Connect arduino pin 4- l293d IN 4 pin 15
•     Connect two motor show like bellow image

Project step 1: read  your IR  remote button value using serial monitor.

            First do the circuit connection shown above and  download the ir remote library file for arduino IDE. And copy the library file in the arduino libraries folder.

And then run the arduino ide select sketch like that given bellow

File -> examples->IR  remote->IR recv demo

Upload the sketch to arduino and open serial monitor. Press the TV IR remote (any company) in front of  ir receiver then you will see the decode hex code in serial monitor (example : FF30CF). the code will vary according to the remote company. Press any 5 button in remote and note down the codes shown in the serial monitor for programming purpose.

Project step2: upload IR robot code  and  play

This is the code for IR robot:

Type your 5  button s code in if else if statement in bellow code. The shown value is my remote value.

Use 5 button to control robot forward, reverse, left right and stop

#include <IRremote.h>

int RECV_PIN = 11;

int statusled = 13;

IRrecv irrecv(RECV_PIN);

decode_results results;

void setup()

{

  irrecv.enableIRIn();

 pinMode(statusled,OUTPUT);

  pinMode(8,OUTPUT);

 pinMode(7,OUTPUT);

pinMode(6,OUTPUT);

pinMode(5,OUTPUT);

pinMode(4,OUTPUT);

digitalWrite(statusled,LOW);// Start the receiver

}

void loop() {

  digitalWrite(8,HIGH);

  if (irrecv.decode(&results)) {

   digitalWrite(statusled,HIGH);

    irrecv.resume();

    if (results.value == 0xFF50AF){     // 0xtype your IR remote button value note down in the previous step

digitalWrite(7,HIGH);

digitalWrite(6,LOW);

digitalWrite(5,HIGH);

digitalWrite(4,LOW);

       }else if(results.value == 0xFF30CF){

digitalWrite(7,HIGH);

digitalWrite(6,LOW);

digitalWrite(5,LOW);

digitalWrite(4,LOW);

    }

    else if(results.value == 0xFFB04F){

     digitalWrite(7,LOW);

digitalWrite(6,LOW);

digitalWrite(5,HIGH);

digitalWrite(4,LOW);

    } else if(results.value == 0xFFD02F){

    digitalWrite(7,LOW);

digitalWrite(6,HIGH);

digitalWrite(5,LOW);

digitalWrite(4,HIGH);

    }else if(results.value == 0xFF9867){

    digitalWrite(7,LOW);

digitalWrite(6,LOW);

digitalWrite(5,LOW);

digitalWrite(4,LOW);

    }

  }

}

That it once you upload it you are ready to go connect the robot with battery and play. I hope that you are all like my project

                                                          Thank you all
