Setup

Before getting started, make sure you have the following parts.

Write Code

Copy the code below into a new Processing project. If you need a reminder of how to do this, revisit the Getting Started Course.

  
//Add Phidgets Library
import com.phidget22.*;

//Define
TemperatureSensor temperature;

void setup(){
  size(400,400);
  
  try{
    
    //Create
     temperature = new TemperatureSensor();
    
    //Open
    temperature.open(1000);
    
  }catch(Exception e){
    e.printStackTrace();
  }
}

void draw(){
  try{
    double mood = temperature.getTemperature();
    //Convert mood to Farenheit 
    //mood = (mood * 1.8) + 32;
    
    //if cold, turn blue, else, turn red
    if(mood < 23){
      background(#0000ff);
      
    }
    else{
      background(#ff0000);
    }
    
    delay(150);
    
  }catch(Exception e){
    e.printStackTrace();
  }
}
  

Run your program. The background will display a blue color or a red color depending on the temperature. You can hold the Humidity Phidget tightly in your hand to increase the temperature.

Practice

1. Modify your code to include the following colors. Blue should be neutral, so depending on your room, you may have to modify the chart.

2. Add text to the screen to express the current mood. The mood should range from “Stressed Out” for Black to “Blissful” for Red with Blue reading “Relaxed”.
