Assign a led widget to a variable

[Utsugi]

Hello Blynkers!

Maybe this is an easy question, but I did not succeed with my tests. What I’m trying to do is:
Perform a for () for 10 iterations, however for each iteration, it will be a new led widget. So I was wanting to assign a led to a variable, something like int X = led_device_a (V20);. I also tried with string, but to no avail. The intention is in the for () function to call the variable x, assigned from a led, to something like x.on (); or x.off ();

Can you post the code you have tried? OR even just the for loop?

Take a look at this example:

C++ Blynk - Code Examples for Basic Tasks (Work in Progress)

#5 Matrix of Randomly Flashing & Coloured Virtual RGB LEDs I posted this last year…but am tossing it in here to keep my group of sketches up to date. Sorry to those not on Local Server… it is not cheap on the energy, however nothing in it is non-recyclable… 72 LED widgets @ 200 energy means you need 14,400 units of energy to load this. This code is compiled on a Wemos D1 mini with OTA programming functionality built in… but it basically should work on most any ESP8266. http://docs.blynk.cc/…

Solved! Thanks Pete. Just one look to the example, and changed my for() starting at 20, so, the int i controls VPin 20 to 24.

The example provided by @GunnerTechTools is in the setup .
if you want to use outside the setup, you need a timer,
otherwise you will disconnects because ‘for next’ is a blocking loop.
