How to block out other ir codes so the receiver only accepts one signal but not any other?
i tried using the else statement but it doesn't work for example
} else {
Serial.println("IR signal received but not recognized");
this is my program
#include <IRremote.h>
#include <SoftwareSerial.h>
#include <Adafruit_NeoPixel.h>
#define PIN 6
Adafruit_NeoPixel strip = Adafruit_NeoPixel(11 * 1, PIN, NEO_GRB + NEO_KHZ800);
IRsend irsend;
SoftwareSerial BT(0, 1); //TX, RX respetively
String readdata;
int vSpeed = 100;
int RECV_PIN = 11;
IRrecv irrecv(RECV_PIN);
decode_results results;
const int speakerPin = 12;
int maxHealth = 5; // Number of times you can get shot before dying
int myHealth = maxHealth;
int deadTime = 1000000000; // Number of ms you stay dead
int deathCount = 0;
int hitState = HIGH;
int lastHitState = HIGH;
void setup() {
BT.begin(9600);
strip.begin();
strip.show();

colorWipe(strip.Color(204, 0, 204), 10);
}
//-----------------------------------------------------------------------//
void loop(void) {
while (BT.available()) { //Check if there is an available byte to read
delay(10); //Delay added to make thing stable
char c = BT.read(); //Conduct a serial read
readdata += c; //build the string- "forward", "reverse", "left" and "right"
