We could add it to the circuit, but we can also use the Arduino Uno built-in LED, which maps to the digital I/O pin #13. We can write a program in this way:#define BUTTON_PIN 3 void setup() { pinMode(BUTTON_PIN, INPUT_PULLUP); pinMode(13, OUTPUT); digitalWrite(13, LOW);...
/*Reading a serial ASCII-encoded string.This sketch demonstrates the Serial parseInt() function.It looks for an ASCII string of comma-separated values.It parses them into ints, and uses those to fade an RGB LED.Circuit: Common-Cathode RGB LED wired like so:- red anode: digital pin 3 th...

Reads a digital input on pin 2, prints the result to the Serial Monitor 从针脚 2 读取数字输入,并打印至串口监视器。 This example code is in the public domain. 此代码示例位于公共域中。 https://www.arduino.cc/en/Tutorial/BuiltInExamples/DigitalReadSerial ...
“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...

hereNote: I have had issues where I change something in the library settings and even when I change it back it no longer works. This is becuase the Arduino IDE doesn't re-compile everything, every time so to get it to re-compile I close the Arduino IDE and re-open it after the ...
Arduino ShiftIn() uses two signal pins (a digital output pin, and a digital input pin - i.e. almost any of the arduino pins) and generates a clock signal on the output, and receives data on the input, using the digitalRead() function. ...
Learn how to use analog reading with ESP8266 using Arduino IDE, MicroPython or Lua firmware. Both ESP8266-12E and ESP8266-07 have one ADC pin that is accessible.
