I have created this project but once the RGB light goes on and low the brightness does not turn off, does anyone help me?

int pinLed1 = 2;

int pinLDR = 0;

int valorLDR = 0;

void setup()           //Prog_11_3
{
  for (int i = 9 ; i < 12 ; i++)
    pinMode(i, OUTPUT);

  pinMode(pinLed1, OUTPUT);

  Serial.begin(9600);
}

void loop()

{
  digitalWrite(pinLed1, LOW);
  valorLDR = analogRead(pinLDR);

  Serial.println(valorLDR);
  Color(random(255), random(255), random(255)) ;
  delay(500);
  if (valorLDR > 500)     //HERE
  {
    analogWrite(A5, HIGH);
  }


  delay (50);
}

void Color(int R, int G, int B)
{
  analogWrite(9 , R) ;   // Rojo
  analogWrite(10, G) ;   // Green - Verde
  analogWrite(11, B) ;   // Blue - Azul
}

You have posted code without using code tags. The code tags make the code look

like this

when posting source code files. It makes it easier to read, and can be copied with a single mouse click. Also, if you don't do it, some of the character sequences in the code can be misinterpred by the forum code as italics or funny emoticons. The "Code: [Select]" feature allows someone to select the entire sketch so it can be easily copied and pasted into the IDE for testing.
If you have already posted without using code tags, open your message and select "modify" from the pull down menu labelled, "More", at the lower left corner of the message. Highlight your code by selecting it (it turns blue), and then click on the "</>" icon at the upper left hand corner. Click on the "Save" button. Code tags can also be inserted manually in the forum text using the code and /code metatags.

Unless the sketch is too large, it's better if you post your code, rather than attach it. When it's attached, we have to download it, create a folder then open your code in our IDE. And afterwards, the folder remains unless we navigate to the "Temp" folder and manually remove it. It's much easier to just view the code in your post.

Many questions can be answered by reading the documentation which is provided with the IDE, available under the help tab, or online here.

There are many other things that programmers do to make their code understandable. Please do them, as a courtesy to the members who volunteer their time to help you here. One is to use a standard indentation to clearly show the code blocks. Never put more than one statement per line. Place any brackets by themselves on a separate line. Use blank lines sparingly, no more than one at a time. Before posting the code, use Ctrl-T in the IDE to reformat the code in a standard format, which makes it easier for us to read. Another is to give things descriptive names. Use descriptive variable names, for example "temperature" instead of "t". You can name numerical constants, pin numbers, variables and many other things in this way. For example, you can refer to a pin and an output level by number, like

digitalWrite(3,0)

. But such a statement doesn't reveal anything about the purpose.

digitalWrite(hornRelayPin, LOW)

does.

Where do you think you have told it to turn off?
