Servo, button and slider controll / hc-05

[Ryato]

I beg your pardon, I am explained badly before.
My goal is to bring both the slider and the button to blynk not just the button

the virtual button activates and deactivates the virtual slider both on blynk

[John93]

What about the sketch, does it work ?

[Ryato]

No, when i send the sketch to arduino the HC05 doesn’t send/recive signal

[PeteKnight]

Do you have the BT widget installed in the Blynk app, and what do you see when you open that widget?

Pete.

[John93]

I’ve modified it again, try it one last time.

[Ryato]

yes i have BT widget and when i open it i see the tex :“connect bluetooth devices”

[lolloi]

I’m the same person of post.
I don’t understand why the HC05 when I upload the code turn on/off random

[John93]

you should provide as much details as possible, like sketch, library version, wiring diagram, etc…

I am using both IDE version 2.0 and 1.8.4.
I’m trying to translate the code written in the post into the Blynk “version”, so both the slider and the button I would like to be virtual (Blynk Legacy).
I’m using the latest versions of all libraries.
The objective of the program is to move the servos using a slider that is activated only when the state of the button is equal to 1.
I attach a video of the version with slider and physical button and a image of arduino’s connection (Physical verson)

What exactly does this mean?

@Ryato

I’m using the latest versions of all libraries.

That’s a bad move as far as Blynk is concerned. I’d always recommend using version 0.6.1 with Blynk Legacy.

If you want to understand how you receive the values from widgets attached to virtual pins then you should read this:

Using Virtual Pins to control physical devices

I thought I’d write a guide about how to use virtual pins with app widgets such as buttons, to control physical devices such as relays, LEDs etc… Why use virtual pins anyway? I’d always recommend using virtual pins over physical pins when developing your code. There are a number of reasons, but here are what I consider to be the main ones: Virtual pins are hardware independent. This means that it’s far easier to port your code from one hardware platform to another in future (when you realise…

I test the program on IDE 2.0 and 1.8.4

@Ryato

I test the program on IDE 2.0 and 1.8.4

Both arduino ide versions should work fine, it doesn’t matter if you were using version 2.0 or 1.8.4 which is too old, the latest version is 1.8.19

I understood the basic concept but I did not understand how to compile the whole program
the app does not even find the hc-06, and those few times there it does not connect

[PeteKnight]

Impossible to comment without further information.

I understood the concept of the article you sent me only that it is explained toolo the part of void setup() and not the loop() and the declaration of variables before setup(), in my case for the servos.
Also because there is no written how to make arduino communicate with blynk and I am afraid that I got the program compilation wrong.

#include <BlynkSimpleSerialBLE.h>
#include <SoftwareSerial.h>

// You could use a spare Hardware Serial on boards that have it (like Mega)
SoftwareSerial DebugSerial(0, 1); // RX, TX

#define BLYNK_PRINT DebugSerial
#define BLYNK_USE_DIRECT_CONNECT
/* Fill-in your Template ID (only if using Blynk.Cloud) */
//#define BLYNK_TEMPLATE_ID   "YourTemplateID"

// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "WbL8ecNmeAicgjcHuLWM9v2Wi5V6ZuAK";

void setup()
{
  pinMode(2, OUTPUT);
}

BLYNK_WRITE(V1)
{
  if (param.asInt() == 0)
  {
    digitalWrite(2, LOW);
  }
  else
  {
    digitalWrite(2, HIGH);
  }
}
void loop()
{
  Blynk.run();
}

Is that correct?

Maybe you be better writing your responses in your native language, because I understand very little of this comment.

@Ryato

Is that correct?

There are so many things wrong with you sketch that it’s difficult to know where to begin.
Why don’t you start with one of the SketchBuilder examples?….

Also, you clearly don’t understand how to use hardware and software serial ports correctly. I suggest that you read this…

Understanding hardware and software serial ports

I’m still seeing frequent posts, mostly from new members of the forum, who are confused about how to add WiFi or Bluetooth connectivity to devices like the Arduino Uno, Nano or Mega, or from people who are trying to use serial communication with some other type of peripheral. I thought I’d try to put together some guidance on how to do this properly. First things first though – if you’re using a device such as an Uno, Nano or Mega that doesn’t have built-in internet connectivity then you shoul…

[Ryato]

Unfortunately I am not very knowledgeable about the whole blynk ecosystem.
And I’ve got about a week to get this whole project done.
Would you be able to convert the program keeping the same function but with both sliers and buttons virtual?

Pls
I am sincerely curious to know how to do it, but I do not have much time.

[PeteKnight]

You almost certainly can’t afford my hourly rate $$$$

Pete.

[Ryato]

I have the money to pay you, but being in a forum I expected that someone could give me a hand, probably for experienced people this program is extremely easy so do not require even so much effort

And as a very important project for my future, I need it…
I’ll try to do it from scratch.
thank you anyway
