Hi, i'm quite new to the Arduino universe and I wanting to try playing around with an IR Receiver but when I tried it, it keeps giving the same message "IR code : 0x0".
While this is in the serial monitor and the "IR code : " part is normal, the 0x0 isn't and it appears even though I didn't press anything on my remote.
Can you please help me ?
By the way, here's my code :
#include "IRremote.h"
int receiver = 11;
/*-----( Declare objects )-----*/
IRrecv irrecv(receiver); // create instance of 'irrecv'
//vairable uses to store the last decodedRawData
uint32_t last_decodedRawData = 0;
void translateIR() // takes action based on IR code received
{
// Check if it is a repeat IR code
if (irrecv.decodedIRData.flags)
{
//set the current decodedRawData to the last decodedRawData
irrecv.decodedIRData.decodedRawData = last_decodedRawData;
Serial.println("REPEAT!");
} else
{
//output the IR code on the serial monitor
Serial.print("IR code:0x");
Serial.println(irrecv.decodedIRData.decodedRawData, HEX);
}
//map the IR code to the remote key
switch (irrecv.decodedIRData.decodedRawData)
{
case 0xBA45FF00: Serial.println("POWER"); break;
case 0xB847FF00: Serial.println("FUNC/STOP"); break;
case 0xB946FF00: Serial.println("VOL+"); break;
case 0xBB44FF00: Serial.println("FAST BACK"); break;
case 0xBF40FF00: Serial.println("PAUSE"); break;
case 0xBC43FF00: Serial.println("FAST FORWARD"); break;
case 0xF807FF00: Serial.println("DOWN"); break;
case 0xEA15FF00: Serial.println("VOL-"); break;
case 0xF609FF00: Serial.println("UP"); break;
case 0xE619FF00: Serial.println("EQ"); break;
case 0xF20DFF00: Serial.println("ST/REPT"); break;
case 0xE916FF00: Serial.println("0"); break;
case 0xF30CFF00: Serial.println("1"); break;
case 0xE718FF00: Serial.println("2"); break;
case 0xA15EFF00: Serial.println("3"); break;
case 0xF708FF00: Serial.println("4"); break;
case 0xE31CFF00: Serial.println("5"); break;
case 0xA55AFF00: Serial.println("6"); break;
case 0xBD42FF00: Serial.println("7"); break;
case 0xAD52FF00: Serial.println("8"); break;
case 0xB54AFF00: Serial.println("9"); break;
default:
Serial.println(" other button ");
}// End Case
//store the last decodedRawData
last_decodedRawData = irrecv.decodedIRData.decodedRawData;
delay(500); // Do not get immediate repeat
}
void setup()
{
Serial.begin(9600);
Serial.println("IR Receiver Button Decode");
irrecv.enableIRIn(); // Start the receiver
}
void loop()
{
if (irrecv.decode())
{
translateIR();
irrecv.resume();
}
}
