Arduino Receiver

Arduino
#include <SPI.h>
#include <nRF24L01.h>
#include <RF24.h>

RF24 radio(7,8);
int LED1 = 3;
const int buzzer = 2;
const byte address[6] = "00001";
int msg[1];

void setup() {
  // put your setup code here, to run once:
  pinMode(buzzer, OUTPUT);
   Serial.begin(115200);
  delay(1000);
  radio.begin();
  radio.openReadingPipe(0,address);
  radio.setPALevel(RF24_PA_MAX);
  radio.setDataRate(RF24_250KBPS);
  radio.startListening();
  pinMode(LED1, OUTPUT);
}

void loop() {

    radio.read(msg, 1);
    String transData = String(msg[0]);
    Serial.print(transData);
    if (transData == "1") {
      digitalWrite(LED1, HIGH);
     } else if (transData == "0") {
