这是一个数字输入,意味着开关要么在闭合状态(从 Arduino 中看到输出 1 或者 HIGH)要么为断开状态(从 Arduino 上看到输出 0 后者 LOW),不会显示之间的值。 The first thing you need to do in the main loop of your program is to establish a variable to hold the information coming in from your switc...

“DigitalReadSerial”示例的功能是读取数字输入，并将结果输出至串口监视器。其代码结构分为三个主要部分：设置函数、循环函数以及注释与说明。设置函数定义了串口初始化和针脚配置。在Arduino IDE的示例代码中，首先初始化串口通信为9600bps，之后将指定的数字针脚（这里是针脚2）配置为输入模式。这样，Arduino...

The Teensy has 21 digital I/O pins and the Teensy++ has 38, which you can use to control many types of devices or read information. You can access the pins by their number, or using their pre-defined names shown in the table. These names match the printing on the circuit board. ...
Arduino 1 2 GPIO.setup("P9_11", GPIO.IN) GPIO.setup("P9_13", GPIO.IN) Now to read the state of the buttons, we would use the commands: Arduino 1 2 state1=GPIO.input("P9_11") state2=GPIO.input("P9_13") state1 will be True if the top button is pushed, and False if ...
You can read back the value of any of the registers. Beware that reading any of the (duplicated) channel registers requires first selecting just one channel: dds.setChannels(MyAD9959::Channel0); uint32_t value = dds.read(MyAD9959::CFTW); // Read the current delta...
With its high resolution rotary encoder arduino compatibility, this dro for milling machine is designed to provide accurate readings and facilitate smooth operation. The BIG LCD display offers clear visibility, making it easy to read and interpret data even in bright environments. The dro is ...
