• There is Tsop output pin is connected to 9th pin of the micro controller, and led +ve pin is connected to 3rd pin of the micro controller

• Tsop 5v supply and gnd , and also led gnd are connected to micro controller supply pins

• After connection to upload program the program code given below slides

Project explanation

• This projects tells about how to control load by using IR remote controller

• There is I preparing , when I press number “1” button led will glow after when press “1” led

STRUCTURE OF PROGRAM

Any program should compulsorily have these two functions– void setup() {……. }– void loop() {…… }

NOTE: The common header files such as stdio.h etc., are included in default.

Step1: Declaring Variables

Integer type variableint ledPin = 3;

This should be declared at the very beginning of the program (Even before void setup() and void loop()).

Step2: Setting I/O pins

• You should set the i/o pins as either input or output using the following function

pinMode(pin number, INPUT/OUTPUT);

• You should declare it inside void setup()

Step3: Writing an Output

To write a value to a pin:

digitalWrite(pin number, HIGH/LOW);

This and all the other functions should be written inside void loop()

Step4: Delay function

• To specify a certain period of time for a set of functions to be executed:

delay(value);

Eg: delay(1000);

It is very important to include this function whenever you want to see an output, as the microcontroller works in micro-seconds speed

Time In milliseconds

Getting input

Step 1: Declare a variable int buttonValue;

Step 2: inside void setup(), initialize pin as inputpinMode(A4,INPUT);

Step 3: inside void loop(), read and store the value.buttonValue = digitalRead(A4);

if-else loop if(buttonValue == HIGH) { digitalWrite(ledPin,HIGH); } else { digitalWrite(ledPin,LOW); }

Since you are checking a condition, you have to use 2 equal-to.

Program Code #include <SPIRremote.h>SPIRrecv remote(9);int ledpin = 3; int irValue;int i = 0;void setup(){ remote.enableIR(); pinMode(ledpin, OUTPUT);}void loop(){ int irValue = remote.getIRValue();

switch (irValue) { case 1: if(digitalRead(ledpin) == HIGH) { digitalWrite(ledpin,LOW); } else { digitalWrite(ledpin,HIGH); } break; } }
