Code for the ESP32 Feather Board

C#
This is the code programmed on the Arduino IDE that needs to be uploaded to the respective boards.
#include "BluetoothSerial.h" //Header File for Serial Bluetooth, will be added by default into Arduino

BluetoothSerial ESP_BT; //Object for Bluetooth

int incoming;
void setup() {
  Serial.begin(9600); //Start Serial monitor in 9600
  ESP_BT.begin("ESP32_LED_Control"); //Name of your Bluetooth Signal
  pinMode(13, OUTPUT);
   digitalWrite(13, HIGH);
   delay(2000);
   digitalWrite(13, LOW);
  
  
}

void loop() {
  Serial.println("5");    
  if (ESP_BT.available()) //Check if we receive anything from Bluetooth
  {
    incoming = ESP_BT.read(); //Read what we recevive   
    if ( incoming == 53)
    {
      digitalWrite(13, HIGH);
      delay(500);
      digitalWrite(13, LOW); 
    }

     if ( incoming == 54)
    {
      digitalWrite(13, HIGH);
      delay(500);
      digitalWrite(13, LOW); 
    }
  }
  delay(20);
}

I have a lot of weird ideas and a degree in mechatronics and that should explain my videos.
