Arduino hardware connection created using arduino, specified as an object. pin— Pin number character vector Pin number on the hardware, specified as a character vector. Note If you are using an analog pin to w
Set the logical value of a digital pin on the Arduino hardware: Sending1to the block input sets the logical value of the digital pin HIGH to 5 V or 3.3 V, depending on the board voltage. Sending0to the block input sets the logical value of the digital pin LOW to 0 V. ...
在 Arduino 程序中，digitalWrite(LEDpin, state) 是一个函数，用于将电平写入数字引脚。该函数有两个参数：- LEDpin：数字引脚的编号。- state：布尔值，表示要写入的电平。如果 state 为 HIGH，则表示将高电平写入引脚；如果 state 为 LOW，则表示将低电平写入引脚。因此，digitalWrite(LEDpin, state...
这是一个抽象函数，其作用是向指定的数字量接口写入数据。在这个例子中，要写入的数字量接口是LED对应的管脚，写入的数据是目标状态，亮或灭。
