Hello,

I am trying to access the LED 2 on the Nano Blinkstick, and there’s no documentation on how to do that. I can access the first one using:

> ```
> public void changeColor(string color)
> {
> foreach (BlinkStick b in blinkStick)
> {
> if (blinkStick != null)
> {
> b.OpenDevice();
> b.SetColor(color);
> b.CloseDevice();
> }
> }
> }
> 
> ```

How can I get LED2 to set the same color?

Please use the function SetColor(byte channel, byte index, byte r, byte g, byte b) to set the color of the second LED:

```
SetColor(0, 1, 255, 0, 0) //Sets color red

SetColor(0, 1, 255, 255, 255) //Sets color white

SetColor(0, 1, 0, 0, 0) //Turns off

```

Hope this helps!

What is the SetColor command for the _first_ LED on the Nano blinkstick?

Is it:

> SetColor(0, 0, 255, 0, 0) //Sets LED1 color red  
> ?

Thanks

@arvydas Please could you tell me the SetColor command in C-Sharp to set the _first_ LED to red on the Nano Blinkstick? Thank you.
