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。

Digital transformation is a set of initiatives that shift enterprises away from manual and analog processes to digital ones in almost every aspect of the business, including supply chain, finance, payroll, HR, customer service, sales, and marketing. Often, an initial step in these projects is di...
In this getting started guide you’ll learn how to read digital inputs like a button switch and control digital outputs like an LED using the ESP32 with Arduino IDE. Prerequisites We’ll program the ESP32 using Arduino IDE. So, make sure you have the ESP32 boards add-on installed before...
