here we make Serial monitor wireless.Because of need for many project like if I make circuit with this
here I can not use normal wire which is used to program the Arduino.and when I want data from this then how.That's why we make serial monitor wireless.
Working:-
Bluetooth two main pin Rx(Receiver) and Tx (Transmitter) These pin can send data and receive data as well.Same here the working.Normally we send the data to Arduino from phone or tablet and many more if you have.
But here Arduino send the data to phone.For get data in phone print on serial monitor we need one software 'Bluetooth Serial monitor.
