Thanx man, you're a hero :-D I had the task to write an app for a customers Arduino project, and I had no idea how to do that easily... you pointed me in the right direction! This MIT App Inventor thing is dope :-D Got it to work, and wrote the app within a few hours... so awesome!!!
I have a question, how can I insert an arrow that doesn't have any bordering backgrplound around if you know what I mean, if I insert photo of arrow there will be white background
Thank you a million times! you inspired me to get an arduino and I've just started and was wondering how to find an app for a project according to my needs and you sir have uploaded the video at the right time. thanks a lot!
Very interesting tuto. I try to implement it but I didn t succed. Is it possible to have de layout of the stepper motor ? What kind of motor do you use ? how to connect it ? Thanks for your help.
Hi, Have you solwed that proplem whit that state text. its one command behind the true command. Shows in your video also. I'm strugling to get it right.
Very nice tutorial. I have a question: when you have written your custom made procedure for a 10m seconds delay why did you add 20 and not 10 to the SystemTime ? Is the clock1 ticking in half millisecond ?
As for the application to control bluetooth, I advise Arduino IO Control, the most convenient and does not require working with MIT Appinventor. You can add joysticks, draw graphs, generate a template for the Arduino sketch.
Thanks for the great video. Found a small bug, I think, where you have to press the LED ON button twice to flush out the text and get correct LED status. Probably text not available if you check for it right after pressing button first time. Fixed it by checking for text in the clock, as oppose to the button event. Create a variable to get the text and if it's not blank then update the LED status. Thanks again.
Hey i made the app exactly as you have shown..Thanks for the tutorial. App is working. only one fault.. when i press ON button the 'LED status' box doesn't show LED ON immediately. i have to push LED On button twice for LED status to show.. same for LED off. i have to press twice to get the status. i checked Arduino code it is fine LED turns on/off immediately. what could be the problem ?
You rock. One question though.. what if I want to send the number 2 or 3 or 11 or 25? I am working on an app on which I have multiple buttons with multiple options.. if 48=0 and 49= 1 does that mean 50=2 and 51=3 etc?
Thanks for your guide on Android Application development. It really helped me. One thing I like to ask about Bluetooth connection is "How to read the Data when available?"
Thanks for this great tutorial.I faced a little problem when getting data from arduino.I can see the data sent from arduino to android in serial monitor,but it's not appearing in the label of app.what could the problem be Thanks in advance for help.
Hi , I am getting an error in the last but one line : Serial.println(“LED : ON”); ; // Stray ‘223’ in program - while verifying the program. Also why is the double semicolons there ?
Nice work, one question please: At 4:01 the ListPicker under HorizontalArrangement2 suddenly changed to BluetoothList. I assume this was not just a rename, but also somehow associated the relevant Bluetooth blocks (as shown later in the first few steps in Blocks editor ). How do I make this association? Without this the bluetooth Blocks do not appear when I switch to the Blocks editor and select the Bluetooth ListPicker. TIA
@chrisj7903 , do I need smth other tahn bluetooth module and arduino, I am asking becaude I don't know what is that orange thing between motor and bluetooth module
I've just managed to create my 1st Bluetooth app which controls 2 water pumps independantly, connected to my arduino uno board using this video as my tutorial and editing the odd bit. Thanks for helping make it possible 👍
I'm not sure if you're familiar with Android Studio, but I'm reading the documentation on connecting Bluetooth devices on Android Studios website, but can't figure out if my phone should be the "server" or the "client"? Anyways, thanks for the videos, man. Your video formats & ways of explaining things are perfect!
After a couple of hours of not getting this to work with the HC-06, I looked at the amazon description of the one I bought and it stated the default serial port rate was at 9600. So all I did is change it in the code from 38400 to 9600 and it worked. Just in case anyone has the same issue.
@@passionnowork4096 Well... it may be five years later, but you solved my problem for me! 😊👍 The place I bought mine from does not have a website with datasheets or useful descriptions, so I was always going to struggle! Thanks.
So happy that it works fine on my arduino pro mini. I want to build an automated indoor garden. But theres one thing I dont get... When I press the Turn On button, the light turns on, but the text on my mobilephone just changes after I press the button for a second time. Maybe the arduino sends the String more then one time, but until now, I dont know how to fix this.
Hi Dejan, so awesome project. I need the same project so badly. I want to set the device to turn a machine knob. The problem I have now is how to set up the wires. Where can I buy all the materials. Thank you very much kindly!
This is probably much too late for OP but anybody who is reading this his code in the video is incorrect. On the blocks that set the texts color depending on connection click the drop down that says text and change it to text color. I struggled for about an hour and it was this simple 😂
@@md.ruhenhossainbhuiyan7808 on the "when clock1 timer" block inside it says "set connected text to" red/blue. Click the dropdown where it says text. Change that to textcolor. Only do that for the ones changing text color not the ones which change the actual text.
Is there a way to do this using wifi instead of bluetooth module? I am asking so that I am able to control it from a further distance or a far away location. Thanks!
Hi i am doing project on automatic spot welding machine so that I need to control 3 controls sequentially for a period of time sequentially so that I need to control the time of every control i.e i need to change the time using potentiometer
Hi , i have a q? does the stepper motor offer more holding torque when it is running in 1/4 steps mode than the full step mode ? i had a problem with the cnc using nema 23 and A4988
Good afternoon, excuse me to know that the materials are taken care of to be able to control the engine well, is that I do not know some and I would like to do well the control Also, could you give me the schematic of how you should connect the entire project please, From the second project
Is it possible to set the brightness of the led (I'd be using a slider bar), while also being able to turn the led on and off with 2 other buttons (using an app)? I can't believe it, but I managed to build an app for hc-05 communication in android studio (took me 2 months to figure out), but I'm having trouble figuring out how to do this
if i use "char" declaration, i must add some delimiter character, it will be difficult on programming, and if i use "string" there is some delay on expression (stepper motor movement).. why?
Really appreciate your tutorials, and hope you can explain something. When I hit the Turn On button the FIRST time, the LED goes on, but nothing shows up in the LED status label. On the next button press, I get "LED ON", whether I press Turn On or Turn Off. On every subsequent button press, I get the status message that I should have got on the previous button press. On closer inspection, I see that is what is happening in your video as well! Any idea why that first button press doesn't produce the correct status message? It puts all subsequent presses/status updates out of sync.
Hi, great tutorial!!! There is a problem If I use the HC-06? what part of the code or in the MIT app ( in the part of blocks) I need to change if is necessary?
i made this app to control my robot. but in the app where it must show the status of bluetooth that whether it is connected or" not connected" it displays some numbers instead of text. can u help me with that?
hi there! first i want to say thank you for this amazing tutorial it is awesome. i have a question; why we are sending 48 and 49, there are meaning 0 1 string? is there a chart to learn these codes?

Awesome! Glad you showed the MIT App Inventor i'm going to take a look at that now as well.
Thanks a lot for the great work. Is there a specific reason that you do not design your app and work based on wifi instead of bluetooth?
Thank you a million times!
you inspired me to get an arduino and I've just started and was wondering how to find an app for a project according to my needs and you sir have uploaded the video at the right time.

Thank you! This is one of the best tutorials I've seen.
got lost a bit in the blocks but its amazing !!

How/where did you get the "Bluetoothlist" under HorizontalArrangement2? Your video skipped right over it. It just magically appeared.
where can i get complete video of the second example?

@BhuvanSridharan do you know how to remove background around arrow for a mit app inventor screen
thanks for agrat video
is it possible to make same app which connects with Arduino by OTG USB cable ?????
you're the Man , i love your tutorials
how did you changed listpicker to bluetooth list?
Thanks for your guide on Android Application development. It really helped me.
One thing I like to ask about Bluetooth connection is "How to read the Data when available?"
When I will press a button let say "A", A will send a value to arduino and when I release A; it will send another value. How can i do this??
There is another function called Touchdown and Touchup for that..
Or you can use toggle button

Thanks!
Wifi is just a connection, it can't actually send or receive anything
Is mechatronics a course? Please reply
I dont understand when you are sending a byte (49) why do you need call BluetoothClient1.ReceiveText and the rest when you are sending?
