Implementing n# attempts to defuse the bomb via keypad

[djairguilherme]

Michael, I have developed some solutions for Escape Room here in Brazil and I have always indicated that my customers buy the Game Timer Pro, because I think the quality is excellent. In some cases, I have customized some needs for my clients. The most recent one involves the possibility that the player has some attempts to set the code via Keypad, before the bomb explodes.

I made the following changes to the code:

In file config.h, add the line:
#define MAXCODES 3

In the GameTimerPro.ino file, in the countdown function – defuse code section:

if (defuseWire == DEFUSE_WIRE_CODE) {
        key = keypad.getKey();
        if (key > -1) {
          if ((!enteringCode) && (key <= 9)) {
            display.clear();
            display.setDisplayColon(false);
            display.printString("____");
            enteringCode = true;
            currentDigit = 1;
            currentValue = -1;
          }

          if (key <= 9) {
            display.setDigitNum(currentDigit, key);
            digits[currentDigit - 1] = key;
            currentDigit++;
            currentValue = -1;
            toggleCount = 0;
          }

          if ((key == KEY_STAR) || (key == KEY_POUND)) {
            enteringCode = false;
            display.clear();
            display.printCountdown(countdownSeconds);
            Serial.println (countdownSeconds);
          }

          // THIS BLOCK HERE IS WHAT I'VE CHANGED

          if (currentDigit > 4) {
            beep(3800, 30);
            int enteredCode = (digits[0] * 1000) + (digits[1] * 100) + (digits[2] * 10) + digits[3];
            countdownRunning = false;
            delay(500);
            if (enteredCode == defuseCode) {
              isDefused = true;
            } else { // HERE
              
              if (currentCode < MAXCODES) { // CHECK IF MAX 
                display.clear();
                display.printString ("_Err");
                enteringCode = true;
                currentDigit = 1;
                currentValue = -1;
                currentCode ++;
              } else {
                currentCode = 1;
                countdownSeconds = 0; // wrong code bomb explodes
                
              }
            } // END CHECK
          }
        }

        // if no current value yet, toggle an underscore
        if ((currentValue < 0) && (enteringCode)) {
          toggleCount++;
          if ((toggleCount % 10) == 0) {
            if ((toggleCount % 20) == 0) {
              display.setDigitChar(currentDigit, '_');
            } else {
              display.setDigitChar(currentDigit, ' ');
            }
          }
        }
      } // if defuse code

Nice work, Djair! Yes, I have made a similar customization for some escape room customers, too. I’m glad you are using the Game Timer Pro in Brazil for different escape room customers! Thank you for your business.
