5 volts will freely flow through your circuit, and when it is not pressed, the input pin will be connected to ground through the 10k ohm resistor. This is a digital input, meaning that the switch can only be in either an on state (seen by your Arduino as a...
Learn how to set the Raspberry Pi Pico GPIOs as digital inputs and digital outputs using MicroPython firmware. As an example, you’ll learn how to read the value of a pushbutton and light up an LED accordingly. With this simple example, you’ll learn how to read any digital input and ...

“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...

In Arduino, there is a built-in function that takes the analog values as input from its pins that are dedicated to the analog values. In Arduino Uno, the pins A0 to A5 are used to take the input values of analog signals and these pins have a pre-installed ADC (analog to digital conv...
