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。

In this project you’ll learn how to read from a digital I/O pin, using the digitalRead() function.Digital I/O pins on the Arduino Uno board are the ones on the USB port side of the board, and they might also be marked as digital on the pins, like in my case:...
Arduino may be build up in JAVA, but its programing syntax is very similar to C++. 2nd step: To build the library you are required to create two files, one with extension .h & other .cpp. In the .h(Header file), you need to write as the following... /...

Note 1: In the Arduino implementation ofdigitalWriteanddigitalReadthere is a check whether the affected pin is used by a timer. It seems 'silly' to do this each time a pin is written or read - as the Arduino developer(s) themselves write in a source comment - so I di...

In a digital (数字) age, we almost never write things by hand. However, many studies have shown that this act has many advantages. New brain research, led by researchers at the Norwegian University of Science and Technology, gets the same result: choosing handwriting is better than using a...
