arduino communication bluetooth


welcome to another arduino tutorial! today we are going to learn how to use bluetooth to exchange data hc bluetooth module. bluetooth is a radio communication protocol that was created as a wireless alternative to the rs serial protocol. today, this technology is popular in connecting two or more mobile devices, particularly smartphones, tablets and laptop computers. we'll be using the hc bluetooth module , a  this tutorial demonstrates how to execute this same process, but wirelessly using bluetooth. we will test this by being able to turn an led on/off wirelessly. you will need to use an adaptor to power your board for this tutorial. this tutorial covers communication from the computer to the board; not from the board to the

mai how does it works? 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 bluetooth module(rx pin of arduino). remember to use a voltage divider on the arduino tx pin bluetooth rx pin download altsoftserial from s pjrc/teensy/td_libs_altsoftserial.html #include altsoftserial btserial; change debug to true to output debug information to the serial monitor boolean debug  basic bluetooth test sketch. hc__ hc zs uses hardware serial to talk to the host computer and software serial for communication with the bluetooth module pins bt vcc to arduino v out. bt gnd to gnd bt rx to arduino pin (through a voltage divider) bt tx to

in this arduino tutorial we will learn how use the hc bluetooth module for controlling arduino via bluetooth communication. you can watch the this is part two of a series, which will focus on using bluetooth to communicate with an arduino. bluetooth is one of the popular wireless communication technologies because of its low power consumption, low cost and a light stack but compensates on range. hc works on serial communication. the android app is designed to send serial data to the arduino bluetooth module when a button is pressed on the app. the arduino bluetooth module at the other end receives the data and sends it to the arduino through the tx pin of the bluetooth module (connected to rx pin of  #eanf#
