To test Bluetooth module.
#include <SoftwareSerial.h>

SoftwareSerial BTSerial(10, 11); // RX | TX

void setup(){
  pinMode(9, OUTPUT);  // this pin will pull the BT Module pin 34 (key pin) HIGH to switch module to AT mode
  digitalWrite(9, HIGH);
  Serial.begin(9600);
  Serial.println("Enter AT commands:");
  BTSerial.begin(38400);  // your own BT Module default speed in AT command mode
}

  // Keep reading from BT Module and send to Arduino Serial Monitor

  // Keep reading from Arduino Serial Monitor and send to BT Module
