Thank you I’ve been trying to figure this out for so long, finally you shared it. I’ve used many of your videos for my projects you’re definitely the best arduino youtuber👍🏻 thanks again

Aha oh my God, I thought I was going to spend days trying to figure this out, it seemed so hard just thinking about it, but the process is much more simple than I thought, huge thanks, God bless you!

Thank you sir, not just for this video but for all your youtube content.

Wonderful tutorial, thank you! Today I ran my first arduino bluetooth connections succesfully and also my first Anrdoid apps. This is interesting !

Man i hope i had found you before your voice is magical i am a student making project and this video helped me alooot 👍🏼👍🏼👍🏼

I love u bro, thanks you LITERALLY saved my life from my teachers ;)

Fantastic, man. Really, really good!

You explained very well. Keep it up. I love it.

now the question that only God can answer, how tf do you only have 250k subs, you deserve 1M+ , best arduino bluetooth tutorial, congrats for the video, you just won another subscriber , continue with the great work

Great video! Thank you so much for making this so easy to follow!

Amazing bro, great tutorial, really thanks

Can you write a program to log data for electronics practicals, like input voltage vs output voltage table or current vs Voltage table, I want to use this to quickly take data for MOSFET, BJT,diode or any other components curves, op amp input/output voltage cirves. Please suggest how can we take data by Arduino, it will save hours of time

Oh. Floating effect wasn't best idea :(

Hello my friend. I want to thank you very much for all you have given to the world very important topics. thank you very much

Excellent tutorial! We want more arduino tutorials

Good job..everything is here! I wii slow it down and watch again but excellent non the less! Thanks.

Brother you literally work as my big brother 😊😊😊❤❤❤❤ No proper video as you I literally beg to have such teacher to me 🤩🤩😚

Thanks for the video. Helpful!

Very useful information, congrats! But I have a question: how did you managed the graph scale and axis? I´ve tried to put them as a background image for the canvas, but it simply didn´t appear...

did you record the video in a boat?

Thankyou so much..this really helped me a lot in my project work..thanks again

Great work thanks to teach us, if you have time kindly make something with that tcs3200 rgb colour sensor, it would be awsome. Thanks once again

Can you explain with multiple sensors data read on mit app

awesome project thank you so much

hey i watch you are video and i will like to ask you HC-06 that need to put a voltage regulator in the Tx portal to make the voltage into 3.3 v how you did it ?

How do you fix the range of the canvas? I'm reading values between 0 and 5 Volts

ELECTRONOOBS YOU SHOULD DEFINITELY MAKE A VIDEO EXPLAINING HOW TO BUILD A CIRCUIT, CODE, APP AND ZERO CROSSING CIRCUIT WHICH CAN CONTROL AT LEAST 5 AC LIGHT BULBS AND BE ABLE TO NOT ONLY TURN THEM ON/OFF BUT DIM EACH ONE OF THEM SEPARATELY VIA BLUETOOTH HC-06 AND ANDROID APP. THAT WILL BE A CHALLENGE!!!

Hey man my bluetooth module isnt connecting to the app I made with MIT app inventor. I use OnePlus 5T , it's Bluetooth v5 . Is that the problem? The s2 terminal works fine but not my app that used to work with my old phone. Do you know what's the problem?

Another great video!

This video is very very useful to me thank you

Thank you for this tutorial. I want to receive data from arduino to app consecutively. How can choose timer interval of the clock in the mıt app inventor to receive data properly?

Very much informative and instructive tutorial. Thank you, brother Andrei.

Thank you so much. I appreciate you!

may i know how to read data when there's two hr-s04 sensors for third project?

Hey i would just want to know that you used label 2 for the value of the data and set it to 0.0 in the text but in the block coding you set label 1 to the received data output in the global variable can you help me out .

finally .... thanks bro .. kip it up...

I thought a voltage divider to drop voltage on bluetooth module receive pin to 3.3 volts was necessary as to not burn up module?

Hi thanks for share this project, Nice tutorial, maybe you can after make one's about MIDI sounds.

Sir please can you help me i used IR sensor in replaced with the HCSR04 but it does not work. What shall i do?

hello i want to thank you for your work and also i need to ask you about a problem that i have... when i try to connect to the bluetooth device i get an error telling me "ERROR 503" and the app cant find the bluetooth devices. what could be the problem? i am using androd 6.0 could this be the problem ?

sir, can I get a voice output from my android about the size of the obstacle using ultrasonic sensor...pls help me sir..

Thank you very much...This Video is very useful for me....

I need to find a way to capture the oscillation point or peak data of a moving object and use that data for a trigger. To visualize this, Picture a rail with a distance sensor at each end. The target would oscillate between the 2 end points with the center being 180. To the left the max measurement would be 270 and max 90 to the right. When the target moves to the right then switches direction I want to capture the farthest measurement lowest number serial data to trigger a device when the target is at a certain point on the left. Then I want to capture the oscillation point highest number on the left to in turn trigger the device at a certain point on the right. Due to changing loads on the device being triggered the oscillation points will change randomly. Can this be done? Below is a rough draft of comments without any code. //Arduino uno // vl53l0x sensors // distance sensor1 value 181 to 270 degrees //distance sensor2 value 179 to 90 degrees //1 stepper Nemo 17 or 23 //Stepper full rotation 0-359 steps (clock wise count 0 north) //Home 180, max rotation from 270 to 90 degrees. // orientations. 270 right, 90 left. //sensors placed at the ends of a rail with oscillating target. //if sensor1 value oscillates set sensor1 to highvalue of oscillation Oscillation at 172-173-172 would set value at 173 // if sensor2 lowalue is = 178 // run stepper to 183 when sensor1 reaches 182 //1degrees // if sensor2 lowalue is =177 // run stepper to 184 when sensor1 reaches 183 // if sensor2 lowalue is =176 // run stepper to 185 when sensor1 reaches 184 // if sensor2 lowalue is = 175 // run stepper to 186 when sensor1 reaches 185 // if sensor2 lowalue is =174 // run stepper to 187 when sensor1 reaches 186 // if sensor2 lowalue is =173 // run stepper to 188 when sensor1 reaches 187 // if sensor2 lowalue is = 172 // run stepper to 189 when sensor1 reaches 188 // if sensor2 lowalue is =171 // run stepper to 189 when sensor1 reaches 188 //Etc....... to lowvalue of 90 //use < at end max run to 270 //If sensor 2 value oscillates set sensor2 to lowvalue of oscillation Ocilation at 186 - 185 - 186 would set value at 185 // if sensor1 highvalue is 182 // run stepper to 177 when sensor2 reaches 178 // if sensor1 highvalue is 183 // run stepper to 176 when sensor2 reaches 177 // if sensor1 highvalue is 184 // run stepper to 175 when sensor2 reaches 176 // if sensor1 highvalue is 185 // run stepper to 174 when sensor2 reaches 175 //Etc........to highvalue of 270....... //use > at end max run to 90.

Good job👍🏼

Thankyou for sharing. Very something for me.

Could this be done with multiple potentiometers where they are all connected to the Bluetooth and transmit data?

Grande you helped us, RdM & FdG SRL

this is a great video!

Is it possible to do it but with a HM -10 I am having problems with connectivity with this module

Thanks, Keep educating. Suggesting make one with WiFi too using 8266

Thanks a lot for this tutorial....it helped a lot. I am successfully sending and receiving data between arduino nano and android phone. But why are you not creating voltage divider for rx input of bluetooth module...which is 3.3v and arduino is supplying 5v through tx output....it might damage hc05 module with 5v in to rx when required is 3.3v.

I'm trying to develop a project like the second app (ultrasonic sensor), but my app isn't working like yours. When I open the app the two labels are colored, the "nothing" and the "detected" too. How can I solve this problem? Could you help me, please?

Hi, did you face any delay in receiving signals to the hc05. I am getting delayed signals and at time it jams. What can be the issue?

Can you show us the "JOYSTICK" app that you have there? I'm tying to create an app that change the screen color of my smartphone when I press a button like a joystick... Thanks

Hi, I have used exactly the same arduino and android code/setup and the same circuit schematic as here and the bluetooth device connects to the app and the serial monitor on arduino IDE shows the correct values. But the application is not able to get the data. I have tried Serial.print and Serial.write but neither work. I reckon this could be because I am using 5V and not taking it down to 3.3V but then in the demo it is also using 5V so I wonder what the issue may be? PLEASE HELP!!!!

thanks a lot for that helpful video

You had drown graph for potentiometer....can we drow graph for ultrasonic sensor ??? If yes, can you send me that Code?

why you dont initialise your RX/TX communication ? i cant receive any data from my arduino help

Without opening Arduino serial monitor or give external power supply to Arduino, then does it show values in Android app??

Wow very amazing tutorials, this is the video i was looking for!! So, can we stop sending data and save graph values ​​then create new graph afterwards? of course without deleting the old graphics. Thank you sir

Hi I coudnt get the detect app to work , the "nothing " and "detected " are both on all the time what could be the reason ?

How can I store data in Arduino sd card via Bluetooth. Like if I want to send an audio to Arduino, then that audio is stored in the SD card in arduino.

Does anyone have any idea why another if statement won't work for more sensors? I can't seem to figure out how to add multiple sensors

Ur great don't worry about life

Do you know how to enroll a fingerprint from R307 and send it to another R307 module via 2 HC05 BT module.... If FPS -A has enrolled the fingerprint then FPS -B should be able to detect the same.. I am using Arduino UNO.

hey man, tghis video gave me a lot of hope for my project could you tell me if it ispossible to use potentiometer or encoder to make circular app searcher??(to find and play certain video for example) ??

I'm to check the multiple conditions in ultrasonic sensor. my code gives 8 random letters. But in if else condition only 1 condition is checked.I've used else if conditions and 8 individual if else conditions but it is checking only single if condition it is not checking the remaining else if conditions.

Which function you used to send data from ultrasonic sensor to arduino

Need more people so spread this video more

Hi... I got a question that I think you could help me. I have an Arduino project with the Fingerprint module. After i finished it, I want to register a new fingerprint to my project but I want to do it without connect it to the computer. But I want to register it through Android Application that I made using the MIT APP INVENTOR. After that I am confuse at how to write the Arduino code ... So I really hope that you can help me to finish this project

Hello I have hd planetary dc encoder motor I want to run it with bluetooth but the thing motor is running with bluetooth but it's not showing the increment values

so cool !! Thanks !

Hi, can I use HC05 module to read data stored on a SD module of the Arduino?

I just bought a HM-10 BLE Bluetooth module, do you think it will work the same way as the HC-06 that you used? Very good video btw

hey, can you show the Arduino LCD readings generated in our mobile phone screen?

can we do the same thing with HC-05 module ?

Hi Thank you for this video .l want to do this with BLE(Bluetooth Low Energy) .do you have idea about this? My code doesn't show data sended!!do you know a source for BLE coding?

How do you move to the connections you want so fast? is that editing or are you using shortcuts

in my case with your app and HC05 module it doesn't work, just showing "???" instead of values sent from arduino

my HC-06 Bluetooth module is not getting discovered in my phone .. how to resolve this?

Excuse me is it possible to store the incoming data we just displayed? If so can u help me or at least tell me how to do that?

Hi electronoobs What if I wanto to plot negative values from a sensor?

Hello thank you for this video. I have a project of controlling the temperature and the pressure in the same time and if there is an issue of this two parameters the application send a message to the technical centre but I have a lot of difficulties

Amazing tutorial thanks

if we use a fire sensor instead.... do the app will change ?

Really a very helpful vedio.

I have followed every step that you did but the text still remain 0. The Bluetooth connection is fine. But it cant display the potentiometer value on the phone. Why did this happen? Please help me I'm working on my final year project.

What if you have several devices, how would I receive an array of data? As I did not see the option of an array data type in the Android mit app developer?

hello, i want to ask you how to read data from arduino on android studio. i tried but always fail. my project is to turn off led automatically after the bluetooth disconnect. please help me.

what is the name of the software you are using in making applications sir? thank you

I dont have HC-06 bluetooth module.. how to pair this with hm-10 ?

Anyone having problems with the bluetooth effecting the analog read values ?. If I disconnect the bluetooth and send to the serial monitor the voltage displays correctly. With the bluetooth connected the voltage bounces up and down by up to 1 volt ( im taking 50 readings and averaging them out to get rid of random jitter)

Do you have a tutorial to get the date & time from a PC via Bluetooth and display it on the Arduino Oled?

hi thank for the info but i need yo help for a project have ph sensor, gas sensor and color sensor

If I need to receive only text message than what should I initialise in blocks

how to send string from HC05 like "start"... how to handle this ..right now am able to receiver only one char and by this making my condition..like char Data_in ; Data_in = USART_RxChar(); /* receive data from Bluetooth device*/ if(Data_in =='1') { do something} but want to send string from my bluetooth device then how to do?

is there a video of you controlling the tank with the app?

Can you show us how to programm a Android app, without this Scatch tool ?
