2. bluetooth

//PROGRAM FOR BLUETOOTH INTERFACE WITH ArduinoNano
//Dani Mardianto
//kirim data 1 untuk menyalakan LED pada D13
//kirim data 0 untuk mematikan0 LED pada D13

const int pinout = 10; // declare pinout with int data type and pin value
int inputdata = 0;  //Variable for storing received data
