My first IoT application. Thx a lot! It was nearly flawless and worked the first time, but I had to change the Serial port baud rate to 9600. Beautiful tutorial video!!!
Thank you very much. I tried like 5 other tutorials and I'm too brain dead to understand the code from the other ones. This code was understandable enough for me to actually apply to my projects.
Really thank you Sir..this principle lead me to develop a number of projects successfully....only thing is the baud rate will be 9600 if you are using HC05
It worked for me, thanks. Can you tell me how to make it work the other way around tho? I need to send the temperature measured by the arduino to my laptop.
Hi Dejan, I'm relatively new to the Arduino world and was wondering if there is a way to connect the HC-05 module to a laptop using the arduino code or is Processing IDE the best option? Any help would be awesome. Thank you!
Hi ! It is a nice video with your flawless narration in English . I note that a lot of people got help from this, to make it work . However i face a problem that the code has uploaded , but i can not find HC -05 appear in my phone module. The truoble is that upto execution of the sketch, your narration goes smooth, but after that you have switched to your own application software instead of a standard available software ( though you mention any other software will work !) And there is no way we can upload your software ( i am waiting !) But I am glad many others have been benifited. Regards.
HI ! Thanks for your reply.Sorry what I meant by your software, was the blue tooth application software that you have shown in the video. You said you will upload how to create that,in the next video.I tried two different blue tooth App from the play store, but on both HC-05 is not appearing on the phone, to select & connect! Regrds.
SIr your tutorials are great! I have a question that if i give the Bluetooth module 3.3 v from the arduino mega board instead of 5v do i need to use the resistors now?
I'm right with you until 5:11, when there is a new, custom application. I'm using "Bluetooth Terminal" app, and it connects okay, but if I try to Send either "1" or "0," nothing happens, and I see >:1 on my smartphone screen, but otherwise nothing. No error messages, and the devices are connected. But nothing... I know I'm doing something wrong, but what is it? Thank you.
Really great video! I've got one question. Please look at the video from 5:39. When you press the TURN ON button, the Led_Status label is "LED OFF" and when you press the Turn OFF button the text on the display is "LED: ON". I Saw that when I press for example the TURN ON button two or more times, the label text is always good, so it is "LED: ON". Every time I need to press two times the other button to get a properly text on the Led_Status label. Could you tell me how to fix this little problem?
from my guess, the text is updating with the previous sent data instead of the new text, i have fixed this by including a fairly large delay between sending the state value and retrieving the text, but there must be a better solution
I was trying your advise but i can't make it happen. I think I don't completely understand your advice. I don't know where to place the delay and what is a fairly large delay?
Dear Sir Thank you so much for the great video .... I have a questions can we change the pairing password for the Module .?????? Could you please let me know ASAP
thats an basic password which comes with bluetooth device hc-05 so if you want change the passward you need to go to the program and change the password in program
Thanks for all your vids! Just smth i don't understand : which compiler/software do you use to create the labtop app? functions like 'fill() or rect(), or background() are not supported by arduino!... thanks
You can try Serial Bluetooth terminal maybe it can set up the connection. Actually i was told this by someone so give it a try, it worked for my friend

Nice vid! I would like to ask you: in which language you wrote the android application and, could it be possibile to have the code of that application (only for learning purpose of course) ?
Is it required that the arduino that being used is must be compatible to the bluetooth module? or there is no compatibility problems? . plss help i'm begginer only
Hi, I'm working on a project. I have to catch ECG signal by using a circuit and send that signal to pc via bluetooth. Can you please tell me the arduino code for this? Thanks in advance. :)
Hi Please, i have a question I have watched your video about Bluetooth and arduino and I want to know can i send audio from arduino to Bluetooth headset by hc05 ? Thank you
Hello sir! Can you help me with some answers? I want to make this project but on Rpi3 model b with also HC-05 bluetooth module. I developed also in MITT APP inventor the code block to connect them but it wasn`t work for me. Do you have any idea how can i make them runnable?
Hi mate .. i want to build desktop app to receive sensor data from arduino via bluetooth module do you have any suggestion which platform i should use ? thanks for replying .. sorry about my english XD
Hi, I made an mobile app using unity but don't know how to connect it to a HC-06 so it will work on my phone off bluetooth. Thanks in advance for any help :)
Sir ,i try to do an application but i needed more one screen in Bluetooth app. So i do what you do in my first screen . But in other screens the module doest response the ordes .but just from the first one.what is the problem?
Is it right that the data that i send to the serial can still be read from the serial monitor in the arduino IDE? I was able to send data from my app but I cannot receive anything from the bluetooth module. When i tried to open the serial monitor, the data that i try to send to the android appears there like normal serial logs. Does it really do that?
Hi! Do you know why I don't have Standard Serial over Bluetooth Link COM port when I want connect to my bluetooth module over PC? My PC pair with module, but can't see COM port? Maybe I need initialize the module with some AT commands, or I need some drivers?
Hi, I tried to light up the led with the computer, but it didn't work. I changed the baud rate to 9600, but still, the led didn't light up. The HC-05 did flash every 2 seconds telling me that it was connected. I am using an Arduino Uno instead of ans Arduino Mega. Thanks for answering me!
I have a small problem. I need to use components that are compatible with Arduino. A position sensor (so I use a GPS module. This GPS module must be Adafruit Ultimate GPS Data Acquisition Module (GPS Included)). A position storage (with an SD card that must work with an SPI link). A bluetooth interface. A GUI to visualize the route (using an Android tablet that is compatible with a bluetooth module). you can advise me to use what as a component . because it's 3 components must be compatible with Arduino and an Android tablet IHM thanks to a Bluetooth module.
I'm having trouble getting the Processing program to work. Any assistance you could provide would be appreciated. I copied the processing program, connected the computer Bluetooth to the HC-05, verified COM5 and COM6 appear in the Device Manager. But nothing happens when I click on either button in the Processing program. If I comment-out the “myPort.write(‘1’); and write(‘0’), then I can get the red border to appear around the buttons. So I assume I have issues comms issues. The comm rate is correct (38400 and 8 data bits, no parity, 1 stop bit and flow control is none) for COM5 and COM6. I can get this program to work from my Android. I wrote a slightly different program than yours but connecting to the HC-05 and sending a 1 lights the LED and a 0 turns it off. Thus I know the HC-05, and Arduino is working correctly. Again, any help you could provide is appreciated.
Здравствуйте. Спасибо за урок. Скажите, пожалуйста, возможно ли с помощью модуля hc-05 связать ноутбук с платой ардуино, работающей в режиме лазерного гравёра? Если возможно, помогите литературкой или ссылками. Спасибо.
my all connections are same as mentioned bluetooth is also connect but led is not glowing i have connected one +ve end the pin 7 and grounded the other end with resistor
Dejan, thanks for this video, its simple and really usefull to me. Can you send me detais or just a image of the code blocks from this aplication, will really help me, since i want to send and receive data from my arduino+HC-05. Thanks dude
I have tried to connect Bluetooth module with laptop.its pairing with laptop correctly but when I press buttons created by processing IDE then nothing happens on pin 13 led of Arduino.when I run processing IDE program Bluetooth module led stops blinking but when I press buttons created by processing IDE code then I get no result and after 2 to 3 minutes Bluetooth module led again starts blinking.which version of processing IDE you are using.please guide me,what I am doing wrong
Can anyone help me? I followed everything he does in the video, but the circuit doesn't work. I have 4 HC-05s and none of them work correctly. I know I am using the 1k, 2k resistors because I grabbed brand new ones and placed them on the board. I can get the AT commands to work, but then when I remove the RX and TX wires from the Arduino mega to upload a program, the Hc-05 stops working. The RX and TX lights on the Arduino mega don't light up either.
Hello sir. Can you help me ? I'm trying to use this module as a master to send information to Android through Amarino app. My module does not come with this "Key" pin. Comes with the "En" pin. But, I can put it put it in AT mode and change your settings to master, change baud rate and other things. As "slave", Android detects. But as "master" Android does not detect. Already I tested with different Android devices, but it still fails. And I have two modules HC 05. But none of them is recognized as a "master" by Android. None of the modules, appears in the Android pairing list. And I also have the "Android Meet" library, installed on the Arduino directory. Why does it happen ? Thank you for your attention !
Thank you for your attention, Sir. I'm also trying to make a SNES controller send data to Android via Amarino and Easymote app. So, last quetion to don't bother you anymore. If I change the role mode to "0" or "2", i can send data(information) to Android ? thank you !
My first IoT application. Thx a lot! It was nearly flawless and worked the first time, but I had to change the Serial port baud rate to 9600. Beautiful tutorial video!!!
Great Channel, Great work, Great videos!
You deserve more viewers and subscribers.
I love your channel! I've watched 3 vids in a row and just subscribed
Spent some time using an app and sending instructions using the 38400 baud rate in your code.
Never worked.
Changed to 9600 and it worked first time.
Disadvantages of being a noob ._.
yeah same here .... works in 9600....
yes. works by changing it to 9600. Thx a lot!
If you do a little bit of research on the HC 05 and HC 06 you'll quickly discover that its default baud rate is 9600.. doesn't take a genious
Most underrated comment here
Thank you very much. I tried like 5 other tutorials and I'm too brain dead to understand the code from the other ones. This code was understandable enough for me to actually apply to my projects.
Glad to hear it! Cheers
I have GW-040 Bluetooth HC-05 module and 9600 baud rate worked for me. I used ArduinoRC android app in terminal mode. Thanks for the great tutorial.
Agreed. Great tutorial, but the default baud rate seems to be 9600.
when downloading to the website, i got an error of Invalid File Type (*.apk)! ? please help
Same error too. Any solution?
Really thank you Sir..this principle lead me to develop a number of projects successfully....only thing is the baud rate will be 9600 if you are using HC05
Thank you so much. Spent a long time trying to use 38400. Although a paper provided with the module says 36400 but works only with 9600.
"simples";Thank You, thats how a tut is done.
Good Job , thanks now i can control Arduino with my laptop using processing.
Earned a subscriber. Great video
Awesome, thank you!
very good tutorial ia have seen even in this topic
Wow this is perfect timing, I almost gave up using bluetooth this week. Thank you! And also thanks for doing a tut on MIT inventor's bluetooth too.
It worked for me, thanks.
Can you tell me how to make it work the other way around tho? I need to send the temperature measured by the arduino to my laptop.

Nice vid! I would like to ask you: in which language you wrote the android application and, could it be possibile to have the code of that application (only for learning purpose of course) ?

i am trying to connect a vr box's remote and a hc05 module. i have tried a lot. please help me.
You have labelled the resistors wrong , 1K is brown black red , 2K is red black red you have them the other way round.
Only the colors are wrong, the numeric labels are right (if anyone else like me got confused)
I did not see any comments stating the color codes for the resistors do not match the shown resistor values (which are correct)
Would it make much difference if I used the HC-06 instead? Since I need it to be slave anyways?
Thanks a lot for responding! I love your channel and website.

Thank you for your attention, Sir. I'm also trying to make a SNES controller send data to Android via Amarino and Easymote app. So, last quetion to don't bother you anymore. If I change the role mode to "0" or "2", i can send data(information) to Android ? thank you !
No problem. Anyway, I really thank you for your attention. Nice Tutorial ! Cheers !
