The Arduino IDE includes the LiquidCrystal library and this library has a number of example sketches. I’ll go over three of them here but you can also try the other ones. You can use these example sketches as a basis for developing your own code for the LCD display module. To access ...

Arduino代码–带LCD的DHT11和DHT22 有时,您会想到一个要在DIY孵化器中监控温度和湿度水平的想法。然后,您可能需要16×2字符LCD来显示培养箱中的主要条件,而不是串行监视器。因此,在此示例中,我们将LCD和DHT11和DHT22传感器连接到Arduino。 接下来,我们需要连接到LCD,如下所示。
#include <dht11.h> //温度传感器dht11库文件 #include <Wire.h> #include <SoftwareSerial.h> //软串口库文件 #include <LiquidCrystal_I2C.h> LiquidCrystal_I2C lcd(0x27, 16, 2); // set the LCD address to 0x27 for a 16 chars and 2 line display ...
