Nopeuspeli Controllinolla

Painonapeilla toteutettu nopeuspeli on tuttu meille kaikille, iloisilla 80- ja 90-luvulla eläneille. (Speden spelit)

Kokeillaan tehdä Controllinon avulla itse tällainen nopeuspeli.

#include <Controllino.h>

const int buttonPins[] = {A0, A1, A2, A3};
const int ledPins[] = {CONTROLLINO_D0, CONTROLLINO_D1, CONTROLLINO_D2, CONTROLLINO_D3};

int gameSpeed = 2000;
int playerScore = 0;

void setup() {
  pinMode(CONTROLLINO_D0, OUTPUT);
  pinMode(CONTROLLINO_D1, OUTPUT);
  pinMode(CONTROLLINO_D2, OUTPUT);
  pinMode(CONTROLLINO_D3, OUTPUT);

  for (int i = 0; i < 4; i++) {
    pinMode(buttonPins[i], INPUT);
    //digitalWrite(buttonPins[i], LOW);  // Use internal pull-up resistor
    pinMode(ledPins[i], OUTPUT);
    digitalWrite(ledPins[i], LOW);
  }

  randomSeed(analogRead(0));

  Serial.begin(9600);
  Serial.println("Tervetuloa, Nopeuspeli neljällä napilla!");
}

void loop() {
  delay(2000);

  int targetButton = random(4);
  int targetLED = ledPins[targetButton];

  digitalWrite(targetLED, HIGH);
  delay(1000);
  digitalWrite(targetLED, LOW);

  int startTime = millis();
  int buttonPressed = -1;

  while (millis() - startTime < gameSpeed) {
    for (int i = 0; i < 4; i++) {
      if (digitalRead(buttonPins[i]) == HIGH) {
        buttonPressed = i;
        while (digitalRead(buttonPins[i]) == LOW) {}  // Wait until the button is released
        delay(100);  // Small delay to avoid continuous registration
        break;
      }
    }
  }

  if (buttonPressed == targetButton) {
    playerScore++;
    Serial.print("OIKEIN! Pisteet: ");
    Serial.println(playerScore);
  } else {
    Serial.println("Väärin! Peli päättyy.");
    playerScore = 0;
    gameSpeed = 1000;
  }

  gameSpeed = max(200, gameSpeed - 50);

  for (int i = 0; i < 4; i++) {
    digitalWrite(ledPins[i], LOW);
  }

  Serial.print("Peli päättyi. Käyttäjä painoi oikein ");
  Serial.print(playerScore);
  Serial.print(" kertaa. Oikea nappi oli: ");
  Serial.println(targetButton + 1);

  delay(1000);
