当您打开Arduino IDE时,为了正确设置IDE,请转到:工具》端口》……,然后选择带有Arduino Uno名称的端口。 对于Windows,它应该类似于“ COM4(Arduino/Genuino Uno)”。 对于Linux,它类似于“/dev/ttyACM0(Arduino/Genuino Uno)”。 ,对于操作系统“/dev/cu.usbmodem1461(Arduino/Genuino Uno)”。 然后转到工具...
int analogvalue = analogRead(A0); temp = (analogvalue * 5.0) / 1024.0; // FORMULA USED TO CONVERT THE VOLTAGE input_volt = temp / (r2/(r1+r2)); 在这里,我们在Arduino的LCD和串行监视器上显示了测量的电压值。因此,在代码中,Serial.println用于在串行监视器上打印值,lcd.print用于在16x2 LCD上...

AREF. Reference voltage for the analog inputs. Used with analogReference(). Reset. Bring this line LOW to reset the microcontroller. Typically used to add a reset button to shields which block the one on the board. Communication The Arduino Uno has a number of facilities for communicating with...
a. uno支持三种供电: 通过外接电源供电(黑圆口,可以接较高电压,传说是7-12V,最好7V) USB供电(通常是USB供电,即写程序时就由PC供电了)。 Vin引脚供电(InputVoltage,一般接电池,连接到这个端口的电源需要稳压,否则非常容易损坏板子,我接过5V使用正常,有传说它和黑圆口是通着的)。
