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 ...
Instead of using the internal pull up resistor from your Arduino board, you could decide to create the circuit yourself and add an external pull up resistor. Your circuit will look like this. Here I have simply added a 10k Ohm resistor between one leg of the button (same side as the dat...

Arduino Nano INPUT_PULLUP Template: The Arduino Nano is a great platform for small projects, and what makes it even better IMHO is having a standard switch/power layout to take your prototypes from 0 to done in record time. This howto will show how to pu

Tested it for all GPIOs that can be a DI. Works for all of them but not for GPIO34 ... GPIO39. They work as input but get not pulled up. Same with INPUT_PULLDOWN. These input-only pins don't have PU/PD circuits. OK, thanks for the information. ...
I'm going to show you how to emulate an Xbox controller with an Arduino, using a USB capable microcontroller and the ArduinoXInput library.
Snap4Arduino is a derivative of Snap!, and is thus also free software released under the AGPL, which is a CopyLeft license. There are different points of view on whether screenshots are derivative works or not, but the practical answer is that nobody will ever come after you for using a...
