Supporting Code Used

You can get your students to  to research libraries and find out how Remote library works This code is to show how the Remote signal works by creating code to support

int irpin = 7;

unsigned long duration;

String Data;

void setup()

{

pinMode(irpin, INPUT);

Serial.begin(9600);

}

void loop()

{

duration = pulseIn(irpin,LOW); 

//when the remote starts it sends a big LOW start bit

if(duration > 5000)  

{

//we clear all data and counters

Data = ""; 

int i=1;   

  while (i < 32) //we count 32 bits of data

{

 duration = pulseIn(irpin,HIGH); 

 i = i + 1; 

if (i > 16 && i <= 24) //we capture the 8 bits of data we want

{

//If light is on for more then 1000us its a 1

if(duration > 1000) Data = Data + 1;

//if light is on for less then 1000us its a 0  

if(duration < 1000)  Data = Data + 0;  

}

}// All 32 bits have counted we now Print our Data

Serial.println(Data);

if(Data=="11001000")

{

  Serial.println("This is  cool"); 

//you can digitalWirite

}

}
