controlling multi led

Using Arduino Project Guidance
1

Hello.
By using the code below we can control one led by voice commands.

how can I edit this code in order to control multi led like 3 or 4 for example

Sounds to me that you are simply blindly copying and pasting code without understanding what it does.

Now you want someone else to figure the code out for you and make the changes?

You had better learn how to program.

3

Why does the code turn italic in the middle?

4

Is this homework?

If you need help, post where you bought the voice module and its documentation.

5

yes I have a project.

I did that and this code is from it's documentation.

But I want to edit it to control multi led because this code for one led.

As I wrote before, learn to program.

I understood it and I had an idea how to edit it,but Iam asking the doctors and mavens in arduino because this was the first step for me in programming arduino and to collect more informations to confirm this code.

Thanks for your attention

Post your sketch.

You are caught in a hard place, as a project, members are always willing to help, but not do the work for you...

However, if the code you posted is a published 'example', you have greater problems. That code sample is an abomination, and hardly worthy of reworking... it needs to be rewritten from scratch!

See if you can contact the author, they may have other better examples to start from. If not, look for a local experienced hacker that can work with you to understand the device and function calls - then develop your solution.

I suspect what you're looking for is doable, but not enough info yet.

Perhaps we all missed the basic question...

how can I edit this code in order to control multi led like 3 or 4 for example

Basic answer:
Add more statements like the following for 2 or 3 more "x" pins...
pinMode(x, OUTPUT);

THen turn them on and off with more of these lines...

digitalWrite(x, HIGH);

digitalWrite(x, LOW);

Under what conditions you want to turn them on and off is up to you.
