首先将VIN引脚连接到Arduino的5V输出,然后将GND接地。 现在,我们只剩下用于I2C通信的引脚了。请注意,每个Arduino开发板都有不同的I2C引脚,应相应地连接它们。在具有R3布局的Arduino板上,SDA(数据线)和SCL(时钟线)位于靠近AREF引脚的引脚接头上。它们也称为A5(SCL)和A4(SDA)。 如果您使用其他Arduino板,请参考下表...

According to this declaration, you must connect RS pin of LCD to digital pin 12, En to 11 and so on. LiquidCrystal lcd(rs, en, d4, d5, d6, d7); LCD Size Till now, we have defined the LCD connection and included its library. After that, we must define the size of the LCD....
the Arduino framework abstracts ports away from the user. I alsofound this Instructables articlethat mentions soldering some wires on to breakout the ports on a Nano board. I have spare Nano's around and if I can make it work I would love to use those for this project rather than the ...
