In this video I use an Arduino with Bluetooth Low Energy BLE and a smart phone app created with MIT App Inventor to control the speed and direction of a gearmotor. The Arduino also reads the motor encoder and send the motor rpm to the Android application. The Arduino version is the Bluno Nano BLE, which is essentially a miniature Arduino Uno with built-in Bluetooth (BLE). In this tutorial, I will explain both the Arduino code and the smart phone application using MIT App Inventor 2.
I have posted the source code here: sciencefuninnovation.gumroad.com

I have been looking for such video all night long! Thank you for sharing knowledge!!

@ScienceFunInnovations 2 года назад

Glad it was helpful! I hope to make more videos like this one soon.

I have spent a couple of weeks trying to get to grips with BLE. There are plenty of examples sending data to the phone but this is the first simple example I have found using MIT app to send BLE messages to the Arduino. Many thanks.

Stay tuned, I am working on a better BLE MIT video. Hopefully it will be out in a month or so.

@@ScienceFunInnovations Excellent. Can you also look into increasing the MTU please? (which may only be possible with WriteBytes instead of WriteString?). I want to be able to save user defined positions for the motor and I have run up against the 23 byte payload limit. Many thanks

Love that you're not super far ahead of where I'm at and can follow along

@JohnDuthie 2 года назад

Okay, this video is a lot more involved. I was referencing some of your older videos.

@ScienceFunInnovations 2 года назад

Glad they are useful.

It's the first time I landed on one of your videos. I've just liked and subscribed. The only advice, you should open your code to the maker community as long as you don't keep a hidden agenda for your channel. Please take it just as a very humble opinion.

@ScienceFunInnovations 2 года назад

Thanks for the tip! I think I found a site where I can start posting my code.

Cool vid man, keep it up

@ScienceFunInnovations 2 года назад

I will

Also, if you have two or screens, you need to put the BLE extension on those pages too.

@ScienceFunInnovations 11 месяцев назад

Only if both pages need BLE communication.

Great vidéo love it im starting up on a project this is all New to me* im working on a project for vidéo équipement. I want to make a slider with whell and i want to make it go slow or fast but also make it move one rotation stop for 30 seconde or mor and go again for a set duration.

@ScienceFunInnovations 2 года назад

Use the interrupt pin and the encoder output to keep track of motor rotation. That way you can make it turn exactly 1 turn and stop.

Hii .. i am using hm10 modules for my product . My question is : will the service uuid and characterstic uuid same for all hm10 modules or is it different from one hm10 module to another hm10 module

@ScienceFunInnovations Год назад

Since that last video, I have learned more about SSID and UUID. I hope to put out a better video in the next month that will explain it better.

@trevmansp 2 месяца назад

Does anyone know how to find out the UUID characteristics and server of my device? I have an M5Stack Core 2, I thought I had found it but I don't think so, because Write doesn't work, if I try in a ble scanner app any one works, but not in the mit app inventor..

@ScienceFunInnovations 2 месяца назад

I do not know. Sorry.

@paolodecaro3741 2 года назад

Good evening, kindly could you post the photo of the hardware assembly and the appinventor and arduino code. From the video I can't see as well as you suggest. Thank you . a greeting from Italy
