智能门锁毕业设计代码部分

由于智能门锁涉及到硬件部分和软件部分，代码部分也分为两个部分：

## 硬件部分
硬件部分主要是通过各种传感器和执行器实现门锁的智能化控制，以下是部分代码：

#include <Servo.h>
#include <Keypad.h>

#define ROWS 4
#define COLS 3

char keys[ROWS][COLS] = {
  {'1','2','3'},
  {'4','5','6'},
  {'7','8','9'},
  {'*','0','#'}
};

byte rowPins[ROWS] = {9, 8, 7, 6};
byte colPins[COLS] = {5, 4, 3};

Keypad keypad = Keypad(makeKeymap(keys), rowPins, colPins, ROWS, COLS);

Servo myservo;

const int servoPin = 10;
const int ledRed = 2;
const int ledGreen = 11;
const int ledYellow = 12;
const int buzzer = 13;

int angle = 0;
int password = 1234;
int inputPassword = 0;

void setup() {
  Serial.begin(9600);
  myservo.attach(servoPin);
  pinMode(ledRed, OUTPUT);
  pinMode(ledGreen, OUTPUT);
  pinMode(ledYellow, OUTPUT);
  pinMode(buzzer, OUTPUT);
}

void loop() {
  char key = keypad.getKey();
  if (key) {
    Serial.println(key);
    if (key == '#') {
      if (inputPassword == password) {
        digitalWrite(ledGreen, HIGH);
        myservo.write(90);
        delay(1000);
        myservo.write(0);
        digitalWrite(ledGreen, LOW);
      } else {
        digitalWrite(ledRed, HIGH);
        digitalWrite(buzzer, HIGH);
        delay(1000);
        digitalWrite(ledRed, LOW);
        digitalWrite(buzzer, LOW);
      }
      inputPassword = 0;
    } else {
      inputPassword = inputPassword * 10 + (key - '0');
      digitalWrite(ledYellow, HIGH);
      delay(100);
      digitalWrite(ledYellow, LOW);
    }
  }
}

## 软件部分
软件部分主要是使用Arduino IDE编写，实现门锁的密码存储和验证、密码输入、舵机转动等功能，以下是部分代码：

#include <Servo.h>
#include <Keypad.h>
#include <EEPROM.h>

#define ROWS 4
#define COLS 3

char keys[ROWS][COLS] = {
  {'1','2','3'},
  {'4','5','6'},
  {'7','8','9'},
  {'*','0','#'}
};

byte rowPins[ROWS] = {9, 8, 7, 6};
byte colPins[COLS] = {5, 4, 3};

Keypad keypad = Keypad(makeKeymap(keys), rowPins, colPins, ROWS, COLS);

Servo myservo;

const int servoPin = 10;
const int ledRed = 2;
const int ledGreen = 11;
const int ledYellow = 12;
const int buzzer = 13;

int angle = 0;
int password = 0;
int inputPassword = 0;

void setup() {
  Serial.begin(9600);
  myservo.attach(servoPin);
  pinMode(ledRed, OUTPUT);
  pinMode(ledGreen, OUTPUT);
  pinMode(ledYellow, OUTPUT);
  pinMode(buzzer, OUTPUT);
  readPassword();
}

void loop() {
  char key = keypad.getKey();
  if (key) {
    Serial.println(key);
    if (key == '#') {
      if (inputPassword == password) {
        digitalWrite(ledGreen, HIGH);
        myservo.write(90);
        delay(1000);
        myservo.write(0);
        digitalWrite(ledGreen, LOW);
      } else {
        digitalWrite(ledRed, HIGH);
        digitalWrite(buzzer, HIGH);
        delay(1000);
        digitalWrite(ledRed, LOW);
        digitalWrite(buzzer, LOW);
      }
      inputPassword = 0;
    } else {
      inputPassword = inputPassword * 10 + (key - '0');
      digitalWrite(ledYellow, HIGH);
      delay(100);
      digitalWrite(ledYellow, LOW);
    }
  }
}

void readPassword() {
  for (int i = 0; i < 4; i++) {
    password = password * 10 + EEPROM.read(i);
  }
  Serial.println("Password is " + String(password));
}
