Arduino Leonardo - Electronic Lock

Placed on 2020-06-22

Now we have most of are functions ready to use so we are able to write the main part of the program.

So first we have to get the EEPROM code if there's already one stored in the EEPROM, then we have to setup the Servo and Initialize the LCD.

I didn't talk about the Auto disable backlight function but it doesn't matter because it's not really difficult to understand.

So this is the code

The Setup and Loop part of the program

void setup() {
  // put your setup code here, to run once:
  GetEepromCode();
  if (EnableServo) {
    Lock.attach(11);
    Lock.write(180);
  }
  InitializationLCD();
  TimeLastActivity = millis();
  if (EnableDebug) {
    Serial.begin(9600);
    Serial.print("LCD Backlight: ");
    Serial.println(LCDBacklightState);
  }
}

void loop() {
  // put your main code here, to run repeatedly:
  Key = customKeypad.getKey();
  if (LockState && Key == '*') {
    CloseLock();
  }

  else if (LockState && Key == '#' && EnablePasscodeChange) {
    ChangeCode();
  }
  
  else if (LockState) {
    OpenLock();
  }

  else {
    lcd.setCursor(0,0);
    lcd.print("Enter Passcode:");
    lcd.setCursor(0,2);
    lcd.print("Press * to validate");
    if (Key = WaitForKey(); Key == '*') {
      CheckCode();
    }
    else {
      GetCode();
    }
  }
}
