参考文章1 参考文章2 arduino的引脚模式有三种: INPUT——输入模式 OUTPUT——输出模式 INPUT_PULLUP——输入上拉模式 Arduino 微控制器自带内部上拉电阻。如果需要使用内部上拉电阻,则应使用pinMode()将引脚设置为输入上拉(INPUT_PULLUP)模式。 上拉电阻 上拉电阻是当某输入端口未连接设备或处于高阻抗的情况下,...

Now that your setup has been completed, move into the main loop of your code. When your button is not pressed, the internal pull-up resistor connects to 5 volts. This causes the Arduino to report "1" or HIGH. When the button is pressed, the Arduino pin is pulled to ground, causing ...

input 和 input_pullup arduino 之间的区别 (1) input.value 绑定 (1) Python2.x中的input()函数漏洞 在Python2.x中,input()函数属于一种危险的函数。如果用户提供的输入包含Python代码,那么这些代码将会被直接执行,从而导致安全性问题。这种漏洞也称为“代码注入攻击”,攻击者可以利用这种漏洞执行任意的Python...
Arduino pins have built-in pull-up resistors on many of the pins (tiny ones, inside the chip just for this purpose), and you can access one by enabling it in the setup: pinMode(buttonPin, INPUT_PULLUP); Change this line of code in your sketch and remove the resistor from your circu...
The Atmega chip on the Arduino has internal pull-up resistors (resistors that connect to power internally) that you can access. If you prefer to use these instead of external pull-down resistors, you can use theINPUT_PULLUPargument in pinMode(). This effectively inverts the behavior, where...

The INPUT_PULLUP option is a Teensy extension which is not present on the official Arduino. Active Low vs Active High Intuitively, most people think of a logic HIGH signal to mean "on" or "active" and a logic LOW signal to mean "off" or "inactive". This scheme is called "Active Hig...
