In this Arduino Tutorial we will learn how to build custom Android applications for controlling Arduino using the MIT App Inventor online application.
For this tutorial we have two example. The first example is controlling a simple LED and the second one is controlling a Stepper Motor using the smartphone. In my previous tutorial we already learned how to make the Bluetooth communication between the Arduino Board (visit Tutorial) and the Smartphone using the HC-05 Bluetooth module and explained the Arduino code needed for the first example.

Awesome! Glad you showed the MIT App Inventor i'm going to take a look at that now as well.

@sothathappened 5 лет назад

Thank you! This is one of the best tutorials I've seen.

@BhuvanSridharan 8 лет назад

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!

@user-db2mv2vx2j 8 лет назад

thank you very much brother really you do exelent tuto

@linegrip Год назад

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!!!

@pines9768 6 лет назад

thanks for sharing

@tgartlan1 7 лет назад

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.

@ashifhossain884 7 лет назад

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.

@user-sj7nu4jb1y Год назад

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?

@marcosluzjunior2348 8 лет назад

nice! well done

@md.nazimuddowla192 7 лет назад

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??

@ahmadadel8259 7 лет назад

There is another function called Touchdown and Touchup for that..

@srikanttangirala3599 6 лет назад

Or you can use toggle button

Hello what kind of servo motor are you using?

@priyanarayan9473 7 лет назад

similarly can we able to create an app using gsm instead of bluetooth?

@apoorvdodiya6153 6 лет назад

why we have used baud rate 38400 instant of 9600 in other HC-05 exaple

@zaheera6899 6 лет назад

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 ?

@mohitagarwal1432 5 лет назад

Hey bro...can you give me the code of this app..

@byronwhitlock6455 6 лет назад

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?

@xiejunquilantang9682 5 лет назад

Do have circuit diagram for the motor? Thanks

@alaincesarini5284 8 лет назад

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.

@chrisj7903 11 месяцев назад

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

@brunodragas8661 9 месяцев назад

@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 👍

@fatonisodiq9341 5 лет назад

hello sir, I have a question for you, how can I move the stepper motor spontaneously when I press the angle (I mean without delay)?

@fatonisodiq9341 5 лет назад

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?

@BHANUPRAKASH-nc8hz 4 года назад

thx but how do i send the data?

@javedmalik1922 6 лет назад

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?

@fredestlulu 8 лет назад

hello , Very good project..... could you tell me what engine you use Arduino + motor interface please? Thanks.

@raoulhatterer957 8 лет назад

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 ?

@formertoddler196 7 лет назад

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

@1anfinity 6 лет назад

Erick i am making a similar project as well. And i am having trouble

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

@akroutsamo 8 лет назад

+Dejan Nedelkovski thank you it was an electric problem not enough current for the motor and the A4988 @1A max pff i need 2.8 A for the nema 23
