Write a HIGH or a LOW value to a digital pin. If the pin has been configured as an OUTPUT with pinMode(), its voltage will be set to the corresponding value: 5V (or 3.3V on 3.3V boards) for HIGH, 0V (ground) for LOW. 如果引脚被设置为INPUT,digitalWrite()会激活输入引脚的上拉电阻。

Arduino GPIO & Digital Input/Output Most of the Arduino boards have low-power CMOS 8-bit microcontrollers based on AVR enhanced RISC architecture. The GPIO pins of these controllers operate at CMOS logic levels. A CMOS gate operating at 5V accepts voltage ranging from 0 to 1.5V as logical LO...

ReadAnalogVoltage, 该demo中出现float类型的变量,死循环函数可以直接用while(1);,或者while(1){},float类型在arduino语言中,只要有一个变量为小数,即可如,5.2/1023.0或者5.2/1023,或者5./1023等等都可以,经测试输出结果保留小数点后两位。 digital blinkwithoutdelay ...
