匯入程式庫 ZIP檔(每個版子有專用的程式庫)

//所需函式
#include<SoftwareSerial.h>
#include<motoLiquidCrystal_I2C.h>
LiquidCrystal_I2C mylcd(0x27,16,2);

void setup() {
  Serial.begin(9600);
  pinMode(13,OUTPUT);
  // put your setup code here, to run once:

//初始化
mylcd.init();
//把背光打開
mylcd.backlight();
}

void loop() {
  // put your main code here, to run repeatedly:
digitalWrite(13,HIGH);
delay(1000);
Serial.println("LED 亮");

mylcd.setCursor(0,0);
mylcd.print("   ");
mylcd.setCursor(0,0);
mylcd.print("LED:OPEN");
mylcd.setCursor(0,1);
mylcd.print("   ");
mylcd.setCursor(0,1);
mylcd.print("DELAY:0.5");

digitalWrite(13,LOW);
delay(1000);
Serial.println("LED 關");

mylcd.setCursor(0,0);
mylcd.print("   ");
mylcd.setCursor(0,0);
mylcd.print("LED:CLOSE");
mylcd.setCursor(0,1);
mylcd.print("   ");
mylcd.setCursor(0,1);
mylcd.print("DELAY:0.5");

土壤濕度-濕度越高 數值越高

找到種成功的地或盆栽 看看他的濕度是多少
以後那個植物就是種那個濕度

#include<Wire.h>

#include<motoLiquidCrystal_I2C.h>
LiquidCrystal_I2C mylcd(0x27,16,2);

void setup() {
  // put your setup code here, to run once:
Serial.begin(9600);
  pinMode(13,OUTPUT);
pinMode(A0,INPUT);//濕度感測
mylcd.init();
mylcd.backlight();
}

void loop() {
  // put your main code here, to run repeatedly:
digitalWrite(13,HIGH);
delay(2000);

Serial.println(analogRead(A0));
//讀出A0訊號並顯示

int value_a0=1023-analogRead(A0);
Serial.println(value_a0);
//定義value_a0是整數
//濕度越高.數值越高


mylcd.setCursor(0,0);
mylcd.print("SM:");
//顯示濕度
mylcd.setCursor(4,0);
mylcd.print(value_a0);
//變數-濕度越高 數值越高
digitalWrite(13,LOW);
delay(1000);
