Codici infrarossi con arduino:
Collegamenti del mio ricevitore IR visto di fronte (sono tutti diversi tra loro, se le spie si spengono sull'arduino stiamo tostando il nostro ricevitore):
Pin a sinistra: dati
Pin al centro: GND
Pin a destra: Vcc

Riporto ora un esempio di come inviare
Codice Arduino per ricevere alcuni determinati codici infrarossi:
In questo codice attiveremo l'uscita 12 di arduino quando riceveremo un certo codice infrarossi, il seguente
Unknown encoding: C26BF044(32 bits)
#define Something_DEC 3261853764
#define Something_HEX C26BF044
Raw (68): 4446 4500 -4450 eccetera eccetera...
Qui il codice per attivare l'uscita ricevuto il nostro DETERMINATO codice IR (aggiungiamo semplicemente "0x" al codice esadecimale):
#include <IRremote.h>
//il codice seguente è per ricevere dati sul led infrarossi ricevente
int receiver =7 ;
IRrecv irrecv(receiver);
decode_results results;
boolean noresult = false;
void setup() {
Serial.begin(9600);
irrecv.enableIRIn();
}
void loop()
{
leggiSensoreIR();
if (results.value == 0xC26BF044 && noresult == false) //premuto tasto avanti
{
digitalWrite(12, HIGH);
}
}
void leggiSensoreIR(){
if (irrecv.decode(&results)) {
Serial.println(results.value, HEX);
irrecv.resume();
noresult = false;
Serial.println(noresult);
}else{
noresult = true;
}
}
//il codice seguente è per ricevere dati sul led infrarossi ricevente
int receiver =7 ;
IRrecv irrecv(receiver);
decode_results results;
boolean noresult = false;
void setup() {
Serial.begin(9600);
irrecv.enableIRIn();
}
void loop()
{
leggiSensoreIR();
if (results.value == 0xC26BF044 && noresult == false) //premuto tasto avanti
{
digitalWrite(12, HIGH);
}
}
void leggiSensoreIR(){
if (irrecv.decode(&results)) {
Serial.println(results.value, HEX);
irrecv.resume();
noresult = false;
Serial.println(noresult);
}else{
noresult = true;
}
}
