arduino uno bluetooth module


mai arduino uno & genuino uno hc bluetooth module hc works on serial communication.here the android app is designed sending serial data to the bluetooth module when certain button is pressed. the bluetooth module at other end receive the data and send to ardunio through the tx pin of  in this project a serial bluetooth module is used to create a connection between arduino uno and an android app that i created with mit app inventor. arduino listens for commands to light some led's or show its status. in addition, a timer interrupt makes it check for temperature via a tmp sensor: if  in this arduino tutorial we will learn how use the hc bluetooth module for controlling arduino via bluetooth communication. you can watch the
