Thanks for all of the wonderful tutorials. I have 1 question about voltage. I've been using the HC-06 module for a few years now on multiple projects and I've never had to convert the voltage to and from 3.3 v. Is converting the voltage just precautionary?
thank you!! no other videos over web showed that a level converter should be used and i have been trying to do it without it and learnt a lesson, i have placed order for a level converter once it reaches me, i'll post the results with a video!!
is the bluetooth module that sensitive towards the 5V from arduino? Is it safe if I just directly supply the 5V from the digital pin from arduino for RX and TX line?
Hi. nice tutorial, i have bought 2 of these modules : Two Channel IIC I2C Logic Level Converter Bi-Directional Module 5V to 3.3V NE. But on the pinout i have AVCC ASCL, ASDA, AGND, BVCC, BSCL, BSDA, BGND, and i don't have the L and H side. can you help me ? Thank you so much! I really appreciate your videos. Have a good night! :-)
Nice, though I will have to watch it again because I lost track of the wiring. :-) I'll be getting a Bluetooth module here pretty soon for my Arduino. So this video was really helpful! :-)
Hi, I got my bluetooth moduals, and the logic converters the other day in the mail. I was trying it out using your app and your sketch. I could not get it to work. I check the wiring and check the voltage points on a logic converter thinking that might have been bad. Or maybe the Bluetooth modual was bad. So just out of curiosity, after a couple hours of playing with it, I tried another Arduino/Android app and it works. Both the logic converter and the Bluetooth modual are working fine. Your sketch works also. So I'm thinking maybe your app that you created using that website is not compatible with the version of Android I'm using. Which is 4.2.2 Jellybean. :-) But thank you for the tutorial, I found this video very helpful, as I did not know about the logic converter. I learned a lot from this video. Thanks again! :-)
+Dog Rox I had the same issue and I also used a different app and it worked ok. However, I have done a few basic things with the MIT App Inventor and they have worked on my phone so not really sure what is going on. May need to see if I can recreate it on App Inventor and see if I get anywhere.
wellofbeersheba I haven't played with it in quite a long time now but eventually will get back into it. I'm glad you posted a comment on this video. I forgot all about it cuz it was awhile ago. it refreshes my memory about what issues I was having back then. Thanks dude!! :-)
Hi, nice idea to connect arduino projects together with an android onces, I wonder how to connect some analog datas from arduino and send them on bluetooth into already exist free aps, like paraglider dasboard, it is available to download from google play store, would like to send data from barometer into that aplication, there is few bluetooth devices they recommend, but they are expensive and one of that projects (australian one), looks like was made on arduino DIY background, what you think, could you connect your bluetooth into this app?
Hey man! Thank you so much for this video! Its greatly helped me on me project but may i know when you will be doing the enhanced version of this with the app on android studios? Im in desperate need of such a tutorial! Oh and btw you got a new subscriber (:! thanks once again!
Guys try this new modern Bluetooth Controller APP, don't forget to share with your friends! play.google.com/store/apps/details?id=com.kopunectomas.smartbluetooth
Hey, Nice video but you could drive the bluetooth module without the level converter! You could make a Voltage divider with two resistors. Anyway nice video again! :)
Hi, thanks for this video. Can you do one explaining how to create a Xamarin Applicaiton for on/off the led thanks to Bluetooth with the phone? Thanks !
Thanks for making these videos. However, a comment .... personally, I don't like the background music. Your videos are good as they are without having to add any sound track. My vote would be no music.
The code on this video is wrong , don't work testcouplage:4: error: expected unqualified-id before numeric constant testcouplage:8: error: expected ',' or ';' before 'void' testcouplage.ino: In function 'void loop()': testcouplage:17: error: 'mySerial' was not declared in this scope testcouplage:17: error: expected ')' before ';' token testcouplage:18: error: 'myserial' was not declared in this scope expected unqualified-id before numeric constant
i really cant work this out.. i want to turn 3 leds on or off.. i cant add anymore then the one on this project.. i can see a "c" what does that mean? send 0 or 1 to c?? im not a complete newbie iv never understood (wirless side of things) lol

i have connected my phone to the Bluetooth module but i could not turn ON/OFF the LED .. led on the module blinks twice every 5 sec approximately .. can any one help me ?
Tamer Esam Yes indeed. Arduino has an onboard 3.3V regulator. That way we get 3.3V at the 3.3V pin. But all the other pins, use 5V level logic which will destroy the Bluetooth module. That's why we need the level converter. In order to lower the 5V to 3.3V to signals coming from Arduino, and to increase level from 3.3V to 5V to signals that the Bluetooth module sends.
I simply wasn't aware of the level difference until I noticed that in your video (sorry for the naive mistake). However my project did run for days without burning the HC-05! Anyway, I am going to correct the bug before it shows up. Thank you!

With the greatest of respect sir. You must work on your audio track quality. In this day and age, and the cost of Chinese made audio products, there is no excuse to fore go proper audio production tech I came to your channel to learn but spend my time trying to understand what you are saying. You are recording the room tone along with your script. The direct reflection from the walls , ( hard slap) are leaking into the microphone, making it more than a chore to understand your version of the descriptive text in what is obviously your second language. I am not going to dance around the topic. I hope I am not rude. But!!! I must be clear. And so will you if you take the time to buy a head mounted mini boom mic, find the sweet spot, do you setup and use it religiously. Remember they tend to improve the bass and some even the high end in some bandwidths. That is because a lavelier (lapel) mic is worn down in the vee of a sweater, and to make them sound natural they do a bit of freq. EQ. Comprendez?? Hard wire means no batteries, just a nice electret condenser and "Bob's you uncle" Don't say I never did something nice for you
