引脚电压定义,high和low当读取(read)或写入(write)数字引脚时只有两个可能的值: high 和 low 。highhigh(参考引脚)的含义取决于引脚(pin)的设置,引脚定义为input或output时含义有所不同。当一个引脚通过pinmode被 39、设置为input,并通过digitalread读取(read)时。如果当前引脚的电压大于等于3v,微控制器将会返回...
Since the pins are not marked on the Mini as they are on the Uno, it’s important to know which pin is which. Above the four digital pins on the right side of the controller are the four analog pins. Unlike the Uno, all of these can be set to read data in or write data out....
Note that pin 4 is default Chip Select (CS) pin for most boards. To set CS for MKR Zero, you can use 28 instead of 4, alt. use the SDCARD_SS_PIN definition. COPY 1/* 2SD card read/write 3 4This example shows how to read and write data to and from an SD card file 5The ...

on and LOW turns it off. Therefore, to turn on pin 13, we need to write ‘HIGH’ to it as shown on line 4 using the ‘digitalWrite’ function. In the digital world, a binary value of1means HIGH or ON, and0means OFF or LOW. However, for Arduino we will stick with HIGH and ...
