Download Arduino AND Bluetooth HC05 Connecting easily Tools Arduino AND Bluetooth HC05 Connecting easily All Show All Items Hello Every body , This is my first artical on Instructable.com , I'm so happy for that , and I will start by How to connect arduino with bluetooth , I suffered a lot of problems when I try to connect it as the website and instructable artical did , So i decided To share my experience with You The bluetooth module I will use today is HC05 which is so familiar and cheap , Most tutorial on The website Connect the bluetooth with default Rx and Tx on the arduino Board , I faced a lot of problem and bluetooth didn't work will . But arduino support something Called Software Serial , which allow You to change any arduino board pin to serial pin http:/rduino.cc/en/Reference/SoftwareSerial so After reading this article you will be able to: 1) Connect arduino Board with PC By Bluetooth , to send and receive data . 2)Connect arduino Board with Any android device . so you can send your information , Like Sensors reading , from arduino to PC Or android device , and you can build your Home automation system by bluetooth , and controlling your robot wirelessly
Step 1: Material and connection

Show All Items We now want to send or receive Data between arduino and computer , first we need to make a Communication link to Definition arduino Board to the computer . We will need a software called Tera Term to show the data received or what we want to send through it . You can download Tera Term or any terminal emulator software , you can download Tera term from this link : http://hp.vector.co.jputhors/VA002416/ttermv14.zip To make a link between your Arduino and bluetooth , do the following : 1) Go to the bluetooth icon , right click and select Add a Device 2) Search for new device , Our bluetooth module will appear as HC05 , and add it 3) The pairing code will be 1234 . 4)after make a pairing , we can now program the arduino and upload a sketch to send or receive data from Computer.

Step 3: Arduino Code
Show All Items As I mentioned before , I will use software serial library to make pin D10 & D11 As Tx & Rx instead of using the default Rx and tx " D0 &D1 On most arduino Board " . this program below allow us to control LED connected to D13 To blink on/off , by press # 1 from PC Keyboard the LED blink on , and if we press 0 LED blink off ! http://instructables-pdf.abuouday.com/download.php

To send the Control commands from Computer to arduino , Go to the tera term , Run it , and choose Serial , and select the bluetooth Serial from the list as Shown on the picture . The code below : // This program shown how to control arduino from PC Via Bluetooth // Connect ... // arduino>>bluetooth // D11 >>> Rx // D10 >>> Tx //Written By Mohannad Rawashdeh //for http://www.genotronex.com/ // you will need arduino 1.0.1 or higher to run this sketch #include // import the serial library SoftwareSerial Genotronex(10, 11); // RX, TX int ledpin=13; // led on D13 will show blink on / off int BluetoothData; // the data given from Computer void setup() { // put your setup code here, to run once: Genotronex.begin(9600); Genotronex.println("Bluetooth On please press 1 or 0 blink LED .."); pinMode(ledpin,OUTPUT); } void loop() { // put your main code here, to run repeatedly: if (Genotronex.available()){ BluetoothData=Genotronex.read(); if(BluetoothData=='1'){ // if number 1 pressed .... digitalWrite(ledpin,1); Genotronex.println("LED On D13 ON ! "); } if (BluetoothData=='0'){// if number 0 pressed .... digitalWrite(ledpin,0); http://instructables-pdf.abuouday.com/download.php

Genotronex.println("LED On D13 Off ! "); } } delay(100);// prepare for next data ... } After uploading This sketch go to tera term and press 0 or 1 and see the results This Video show the results of this code .
Step 4: Connect arduino To android Device Show All Items after we finished from connecting arduino with PC By bluetooth , let's move to how we can connect arduino To android device . at first you need a terminal emulator on your andriod device to send or receive data to arduino . You can download this app from Google play . https://play.google.com/storepps/details?id=arduino.bluetooth.terminal&feature=search_result#? t=W251bGwsMSwxLDEsImFyZHVpbm8uYmx1ZXRvb3RoLnRlcm1pbmFsIl0. http://instructables-pdf.abuouday.com/download.php

after that , you can use the same arduino Sketch and control LED Blinking on or Off from android device . just type and t send #1 to make LED Blink on , or 0 to blink off . this video below show how to control arduino I/O from android tablet .
Step 5: Receiving Data from arduino Show All Items The last arduino Sketch that i wrote , used to send commands from PC Or android device to android , Now in this program i will use arduino to Calculate the time since the start of the program in second , and send it Via bluetooth to any pairing device . the code below // This program shown how to control arduino from PC Via Bluetooth // Connect ... // arduino>>bluetooth // D11 >>> Rx // D10 >>> Tx //Written By Mohannad Rawashdeh //for http://www.genotronex.com/ // you will need arduino 1.0.1 or higher to run this sketch #include // import the serial library SoftwareSerial Genotronex(10, 11); // RX, TX int ledpin=13; // led on D13 will show blink on / off long previousMillis = 0; // will store last time LED was updated // the follow variables is a long because the time, measured in miliseconds, // will quickly become a bigger number than can be stored in an int. long interval = 1000; // interval at which to blink (milliseconds) int ledState = LOW; // ledState used to set the LED long Counter=0; // counter will increase every 1 second void setup() { http://instructables-pdf.abuouday.com/download.php

// put your setup code here, to run once: Genotronex.begin(9600); Genotronex.println("Bluetooth On please wait...."); pinMode(ledpin,OUTPUT); } void loop() { // put your main code here, to run repeatedly: unsigned long currentMillis = millis(); if(currentMillis previousMillis > interval) { // save the last time you blinked the LED previousMillis = currentMillis; Counter+=1; Genotronex.println(Counter); // if the LED is off turn it on and viceversa: if (ledState == LOW) ledState = HIGH; else ledState = LOW; // set the LED with the ledState of the variable: digitalWrite(ledpin, ledState); } } at the end , You can visit the orginal artical in arabic language on my website http://www.genotronex.com/ Hope my first artical here is useful to you , thank you for your time ,
