You’re welcome. All the information that you need is in this blog post (schematics and code).

Thanks for asking,
Rui

Im trying to do a similar thing like this tutorial.
I want to turn leds (in one circuit) with the android, but when it turns off (by a sensor) I want to another led (in another circuit, separately) turns on and when it turns off (by a sensor)……. and go like this with 8 circuits.
How can I do that?
Regards.

hello rui santos, it can happen even without the bluetooth module … is by using a USB OTG like this video https://www.youtube.com/watch?v=yaifCo8u7T8

Can you make a tutorial like the video, and make it free. I would much like to thank to you!

I wonder if anyone can help me with my problem. I am trying to finish this project as my thesis but after a month trying different ways to solve it, I really don’t know what else to do now.

I am building my app with App inventor 2 and with my arduino. I have a gas sensor which via bluetooth sends the numbers to the app and whenever the value of the gas increases the phone has to give a notification and to speak some text.

My problem is that I am trying different ways of receiving the value and I can not find the correct way to receive the numbers and then with a math block is needed to compare if that value is higher or lower than another value.

So I will explain what I have and let’s see if it helps you to understand what I am doing wrong:
Inside the timer it checks first if the bluetooth is connected, if so, set variable Sensor to Call Bluetooth BytesAvailableToReceive. And if button On is not enabled, set value text to get global Sensor.
And right after that it comes the comparison, if get global Sensor is higher or equal than 700 then set Color Alarm red, call notification and call VoiceAlert.

And here I just receive a number 1 on my label value. I have also tried different ways of receiving the value but none of them has worked yet, so if you could please help me to solve this I would really appreciate it.

Thank you in advance for your help.

Carlos.
