This document describes an Arduino-based remote control project that uses an IR receiver module to control an LED. The circuit connects the TSOP output pin to the Arduino's pin 9, and connects the LED and resistor to pin 3. The Arduino code uses the SPIRremote library to receive IR signals from the remote. When button "1" is pressed, it toggles the state of the LED connected to pin 3. The code uses an if/else statement within a switch case to change the LED from on to off or vice versa each time button 1 is pressed on the remote.

4. • 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

5. 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
will off

11. 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.

12. Step1: Declaring Variables
Integer type variable
int ledPin = 3;
This should be declared at the very beginning of
the program (Even before void setup() and void
loop()).

13. 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()

14. 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()

15. 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

16. Getting input
Step 1: Declare a variable
int buttonValue;
Step 2: inside void setup(), initialize pin as input
pinMode(A4,INPUT);
Step 3: inside void loop(), read and store the value.
buttonValue = digitalRead(A4);

17. 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.

18. 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;
}
}
