Ifs/Thens with DHT22 with LEDs

Hello,

I’d like to have a setup involving three LEDs with my current weather station while still logging data. I was wondering if you all know if it would be possible for the DHT22 temperature reading to impact LEDs. I currently just have one just to stay on while the station is running. How could I go about having one LED turn on if the temperature is less than 65F with the other two being off, a different one turn on for temps of 65-85F with the other two off and a third one turn on with the other two being off for temps greater than 85F?

Here is my code for my current weather station. Thanks.

How could I go about having one LED turn on if the temperature is less than 65F with the other two being off, a different one turn on for temps of 65-85F with the other two off and a third one turn on with the other two being off for temps greater than 85F?

//global LED pins
const byte led1Pin = 5;  // wired output - R - Gnd  High = illuminated all 3
const byte led2Pin = 6;
const byte led3Pin = 7;


// in setup()

pinMode(led1Pin, OUTPUT);
pinMode(led2Pin, OUTPUT);
pinMode(led3Pin, OUTPUT);


// in loop()

if (t >= 85.0)
{
  digitalWrite(led3Pin, HIGH);
  digitalWrite(led2Pin, LOW);
  digitalWrite(led1Pin, LOW);
}
else if(t >= 65 && t < 85)        //65 to 84
  digitalWrite(led3Pin, LOW);
  digitalWrite(led2Pin, HIGH);
  digitalWrite(led1Pin, LOW);
else                                       //less than 64
{
  digitalWrite(led3Pin, LOW);
  digitalWrite(led2Pin, LOW);
  digitalWrite(led1Pin, HIGH);
}

Thank you so much!
