arduino 简易智能花盆

编辑器：arduino IDE

主板：arduino uno

传感器：

0.96寸的OLED屏（四脚）
声音模块
土壤温湿度模块
DS18B20温度模块（这里用到防水的）
光敏电阻模块（买成三脚的了只能显示高低，可换四脚显示数字） 
arduino扩展板 （看个人需求）
杜邦线（母对母，公对母）
 

功能：能在OLED屏上显示出传感器的数据，并模拟显示出植物对应的状态的图案
可自己设置零界点

（买的少的话pdd即可，百元以内轻轻松松，还可以买个wifi模块，做个app上位机）

代码如下：

#include <OneWire.h>
#include <DallasTemperature.h>
#include <SoftwareSerial.h>


#define SCREEN_WIDTH 128
#define SCREEN_HEIGHT 64
#define OLED_RESET -1
Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET);

const int temperatureSensorPin = A0;  // 温度
const int lightSensorDOPin = 7;  // 光敏
const int soilMoistureSensorPin = A2; // 湿度
const int soundSensorPin = A3;  // 声音

void setup() {
  Serial.begin(115200);
  display.begin(SSD1306_SWITCHCAPVCC, 0x3C);
  display.setTextColor(WHITE);
  display.clearDisplay();
  display.display();
  delay(2000);
  display.clearDisplay();
  display.setTextSize(1);
  display.setTextColor(SSD1306_WHITE);
  sensors.begin(); // 初始化DS18B20传感器
  pinMode(soundSensorPin, INPUT); // 初始化声音传感器引脚
  pinMode(lightSensorDOPin, INPUT);  // 设置数字光敏传感器的数字输出引脚为输入
