IR Transmit_Bluetooth_RGB LED

Arduino
For convenience purposes, this project uses infrared values except for the Hex code.
However, I recommend you use normally the infrared value of the hex code.
#include <SoftwareSerial.h>
#include <boarddefs.h>
#include <IRremote.h>
#include <IRremoteInt.h>
#include <ir_Lego_PF_BitStreamEncoder.h>

SoftwareSerial btSerial(7, 8);
IRsend irsend;

int red = 6;
int green = 5;
int blue = 4;

void setup() {
  Serial.begin(9600);
  btSerial.begin(9600);
  pinMode(red, OUTPUT);
  pinMode(green, OUTPUT);
  pinMode(blue, OUTPUT);
}
void loop() {
  byte data;
  data = btSerial.read();
  if(data == 'A') {
    irsend.sendNEC(106206, 16); 
    digitalWrite(red, HIGH);
    digitalWrite(green, HIGH);
    digitalWrite(blue, HIGH);
  }
  else if(data == 'B') {
    irsend.sendNEC(12495, 16);   
    digitalWrite(red, HIGH);
    digitalWrite(green, LOW);
    digitalWrite(blue, LOW);
  }
  else if(data == 'C') {
    irsend.sendNEC(6375, 16); 
    digitalWrite(red, LOW);
    digitalWrite(green, HIGH);
    digitalWrite(blue, LOW);
  }
  else if(data == 'D') {
    irsend.sendNEC(31365, 16);

Looking back on my childhood, I was happy when I was making something and I was proud of myself. "Making is instinct!"
