Menus not changing when button is pressed TFT 128 x 128
You can make things much simpler:

int count = 0;
int button = 5;
int buttonStatus;
unsigned long timer = 0;

void setup() {
  Serial.begin(9600);
  pinMode(button, INPUT_PULLUP);
}

void loop() {
  buttonStatus = digitalRead(button); // read the button status
  if (buttonStatus == LOW) {
    if (millis() - timer &gt; 200) { //de-bouncing the button
      count++; // increase +1 each time button is pressed
      // clear screen function should be here
      timer = millis();
    }
  }
  if (count &gt; 3){ // if count is bigger than 3 start over.
    count = 0;
    // clear screen function should be here
  }
  switch (count){
    case 1: // if count == 1
    // show charecter :)
    break; // break out of this case!
    case 2:
    // show charecter :(
    break;
    case 3:
    // show charecter :D
    break;
    default: // if none of above cases is valid
    count = 0;
    // clear screen function should be here
  }
  Serial.println(count);
  delay(100);
}

So each time button is pressed count value will increase by 1. you can also add another button to decrease this value...

You might also notice when pushing the button it'll count more than once, you'll also need to De-Bounce the button. tutorial.

Edit: added de-bounce function.
