Bluetooth Slider

How can I use multiple slider so that it all can perform different electricity at the movement?

Are the sliders going to be on a web page ?
If so, do you know how to code the HTML to draw them ?

Hello,

This is a much too much unprecise question to give an answer.

No it is a app called bluetooth electronics.

Hello
How can I control brightness of led through bluetooth. Through slider

I want to control 5 led through bluetooth and I want that I can control all different brightness. I meant to say that i want 5 leds with different brightness through bluetooth

Please fins the attached screenshot where there are 5 slider and from that I want to control 5 different led

Here I am mention to get bluethooth code please help

You mention getting a value from Bluetooth, by which I presume you mean the value of dataIn, but where in the program is its value set apart from when it is declared ?

By the way, tests like this

if (dataIn == '43')

won’t work because a char variable, such as dataIn, can only hold a single character

This thread is starting to cover the same ground as @krishna_agarwal’s other topic:

@krishna_agarwal it’s OK to have separate topics for distinct subjects related to the same project, but we must be careful not to allow them to converge.

This value will get it from side a bluetooth slider when I will slide it will change the value of the power

How can I control brightness of led through bluetooth. Through slider

I want to control 5 led through bluetooth and I want that I can control all different brightness. I meant to say that i want 5 leds with different brightness through bluetooth

Please tell that my code is right or not or if not so what is the mistake please tell me so that I can correct it.

I am new I apologize for that. But this is the another topic that privious topic for check and this topic is for bluetooth.

I understand that, and as I said it’s OK. I’m just pointing out a potential problem.

The app has to transmit values to the Arduino and then they can be interpreted. What hardware have you got connected to the Arduino to receive a Bluetooth message and pass it to the Arduino ?

I have connected HC-05 module, And I am using a app name as bluetooth electronics

How have you connected the HC-05 to the Arduino ?

Yes I think it must be connected to arduino only.

And then I connect from my mobile

It must be connected to the Arduino and you say that you have done that, so which pins is it connected to ?

There is no issue of connection It is successfully connected to the arduino But I presume that my phone is not giving signal to arduino. As my led dose not on when I press on

a successful blue-tooth-connection is not all.
You have to successful read in the values into the arduino
This reading-in is a NON-bluetooth-issue

Smartphone–bluetooth----------HC05----------Arduino-IO-Pins-------Arduino-Program

Arduino-Program is wrong

Post Arduino-Testcode

Please humour me and describe how the HC-05 is connected to the Arduino. The HC-05 has 6 pins if I remember correctly so what are they connected to on the Arduino and which Arduino board do you have ?

I repeat. Where in your code does the Arduino read the input from the HC-05 Bluetooth module ?
