Lane of Things - Emotion Collection

We created a box with buttons that represent a positive or negative emotion. Through these buttons we were able to see what emotion was felt

Emotion Collection

Arduino
It checks whenever a green or red button is pressed and it stores it in variables. These variables are then logged into google sheets.
// *** variables for our LEDs
int redPin = A4; 
int greenPin = A3;
   
int redValue = 255; 
int greenValue = 255;

// *** variables for buttons
const int posButton = 0;
const int negButton = 1;

// *** the variables to calculate happiness
  bool ovEmotion; // if true, people are more happy. If false, people are more sad
  int amtPressed; // how many times any button was pressed
  int happyPressed; // amount happy button was pressed
  int sadPressed; // amount sad button was pressed
  double ovHappy; // a number less than one, % of how many people are happy
  double ovSad; // a number less than one, % of how many people are sad

void setup() 
{
    // *** Set up for the LEDs
    pinMode(redPin, OUTPUT);
    pinMode(greenPin, OUTPUT);
    
    // this could be the command to turn off the LEDs. Test later
    analogWrite(redPin, redValue);
    analogWrite(greenPin, greenValue);
    
    // *** set up for the buttons
    Serial.begin(9600);
