@kaushik it follows video with 3 potentiometers that simulate 3 sensors.


Until Sunday, I will do a tutorial with 3 real sensors: temperature / humidity, proximity and current.

@Taifun In my last tutorial (16) That I posted above I used your bluetooth tip

Hello Nilton. What is important to us in a tutorial is that it teaches best practice.

15

@ChrisWard Hello, it took you almost two months to answer. Well, as you noticed, I'm not an expert on APP Inventor, what I'm doing, or I think I am, is trying to arouse interest in those who know Arduino, and use APP Inventor.
If my videos don't show the best practices, you can remove them.
Tks,

?
I only saw your videos for the first time last night (UK time) Nilton, that was because Kaushik put in a request post. I have proposed publishing guidelines and an approval mechanism for tutorials but MIT always have more work than they can handle.

17

@ChrisWard Well, if Kaushik posted a request, you have to talk to him, I was trying to help him.
Now, you commented on my videos about not being in accordance with good practices, in this case, as I said, someone should have commented this before these 2 months and as I mentioned if they are not in agreement, you can delete them. I think you could have commented in private. See, I just wanted to show the powerful tool that is App Inventor com o Arduino. I was excited to do a multimeter and a remote control with APP Inventor and Arduino, but you get me discouraged.

Nilton, I commented on your remarks which were out of turn in response to friendly advice by Taifun and ABG, both of whom are App Inventor experts and long-established Power Users, concerning your code error. There are around 400,000 Users of App Inventor per month and we (The Power Users) keep things going as unpaid volunteers. So I hope you can understand our position. We welcome Users helping other Users, but if we spot mistakes that could affect many, of course we are concerned and make comments. There is nothing wrong in wanting the best for everyone is there?

@ChrisWard, I think, you did not see my comments? "@Taifun In my last tutorial (16) That I posted above I used your bluetooth tip". I mean, I understood, I fixed, and your comment was delayed. That is the point. The Taifun and ABG comments was before. You are going back to the beginning. Look, my videos that are here, they are not according to the best practice, them, please, delete them, I think 1 person less between 400,000 will not make the difference for you. tks

I think overall your videos are great Nilton and will help others for sure. The software development industry is very tough, very demanding and often rather direct and practical. We are a friendly bunch here, don't take offence where none is intended.

If we need to perform a certain function and the return value is not needed for anything, we can use this block:

@Patryk_F Or, if we have an unwanted function, we can use:

hi nilton can you teach me how to fetch realtime data like weather of a place from google or an api website in an app?

24

thanks i modified as per my requirement and its perfectly working

25

thanks for helping

26

I am happy to can help you

27

Good. I think you understand the way of doing it and can continue to develop

28

it's a challenge for me, I'll see and if I can, I'll post it.

29

ok i found out the coding and app coding can i tell the code

30

@kaushik hi, of course. Please send me.

31

ok

void setup() {
Serial.begin(9600);
}

void loop() {

int s1 = digitalRead(A0);
int s2 = digitalRead(A1);
int s3 = digitalRead(A2);

Serial.print("TEST|");
Serial.print(s1);
Serial.print("|");
Serial.print(s2);
Serial.print("|");
Serial.println(s3);
delay(1000);

}
