I need help with my Arduino IR sensor and IR remote. I'm actually new to Arduino I just bought my first Arduino kit around 20 October 2022 so I was trying to make a simple thing with my IR things like when I press my remote's button the led with blink but when I saw tutorials on youtube.. it doesn't work I wasted my past few hours doing it so please help me at least make my newbie time with Arduino good
This is the code I just copied from a random article
#include <IRremote.h> //including infrared remote header file
int RECV_PIN = 7; // the pin where you connect the output pin of IR sensor
IRrecv irrecv(RECV_PIN);
decode_results results;
void setup()
{
Serial.begin(9600);
irrecv.enableIRIn();
{
void loop()
{
if (irrecv.decode(&results))// Returns 0 if no data ready, 1 if data ready.
{
int results.value = results;// Results of decoding are stored in result.value
Serial.println(" ");
Serial.print("Code: ");
Serial.println(results.value); //prints the value a a button press
Serial.println(" ");
irrecv.resume(); // Restart the ISR state machine and Receive the next value
}
Confirm the sensor output is going to Arduino pin 7.
Try this:
#include <IRremote.h> //including infrared remote header file
int RECV_PIN = 7; // the pin where you connect the output pin of IR sensor
IRrecv irrecv(RECV_PIN);
decode_results results;

//********************************************^************************************************
void loop()
{

if (irrecv.decode(&results)) //this checks to see if a code has been received
{
if (results.value != 0xFFFFFFFF)
{
Serial.print("Code: ");
Serial.println(results.value, HEX); //prints the hex value a a button press
}
irrecv.resume(); // Restart the ISR state machine and Receive the next value
}
} //END of loop()

Your topic has been moved to a more suitable location on the forum. Installation and Troubleshooting is not for problems with (nor for advice on) your project.
uhm excuse me sorry for late reply but when I try that code it says
14:41:49.393 -> The function decode(&results)) is deprecated and may not work as expected! Just use decode() without a parameter and IrReceiver.decodedIRData.
