arduino lcd 1602显示器，火焰传感器，按键，蜂鸣器加入sim800c 的arduino ide程序

好的，以下是根据您的硬件和需求进行调整的示例代码：

#include <SoftwareSerial.h>
#include <LiquidCrystal.h>

#define SIM800_RX_PIN 10
#define SIM800_TX_PIN 11
#define SIM800_BAUDRATE 9600

SoftwareSerial sim800(SIM800_RX_PIN, SIM800_TX_PIN);

#define FLAME_SENSOR_PIN A0
#define BUZZER_PIN 8
#define BUTTON_PIN 2

LiquidCrystal lcd(12, 11, 5, 4, 3, 2); // RS, E, D4, D5, D6, D7
bool flame_detected = false;

void setup() {
  Serial.begin(9600);
  sim800.begin(SIM800_BAUDRATE);

  lcd.begin(16, 2);                // initialize the lcd
  lcd.backlight();                 // turn on backlight
  lcd.setCursor(0, 0);
  lcd.print("Flame Detector");
  lcd.setCursor(0, 1);
  lcd.print("Initializing...");

  pinMode(FLAME_SENSOR_PIN, INPUT);
  pinMode(BUZZER_PIN, OUTPUT);
  pinMode(BUTTON_PIN, INPUT_PULLUP);
}

void loop() {
  if (digitalRead(BUTTON_PIN) == LOW) {
    lcd.clear();
    lcd.setCursor(0, 0);
    lcd.print("Sending SMS...");
    delay(1000);

    String message = "Flame detected!";
    sim800.println("AT+CMGF=1"); // configure SIM800C to send SMS in text mode
    delay(1000);
    sim800.println("AT+CMGS=\"+1234567890\""); // replace with recipient's phone number
    delay(1000);
    sim800.println(message);
    delay(1000);
    sim800.write(0x1A); // end of message
    delay(1000);

    lcd.clear();
    lcd.setCursor(0, 0);
    lcd.print("SMS Sent!");
    delay(1000);
  }

  int sensor_value = analogRead(FLAME_SENSOR_PIN);
  if (sensor_value > 500) { // adjust threshold
    if (!flame_detected) {
      flame_detected = true;
      lcd.clear();
      lcd.setCursor(0, 0);
      lcd.print("Flame Detected!");
      digitalWrite(BUZZER_PIN, HIGH);
    }
  } else {
    if (flame_detected) {
      flame_detected = false;
      lcd.clear();
      lcd.setCursor(0, 0);
      lcd.print("               ");
      digitalWrite(BUZZER_PIN, LOW);
    }
  }
}

请注意，您需要安装LiquidCrystal库和SIM800L库。此外，请根据您的需求更改代码中的代码行，例如更改短信接收者的电话号码和火焰传感器的阈值。另外，请确保您已经正确连接您的硬件，并已正确设置您的SIM卡和SIM800C模块，以使其能够发送短信。
