ADC0-ADC5 其实是作为 PC0-PC5 的第二功能存在的,分别对应 Arduino 定义 A0-A5。也正因为次,在 Arduino 的官方指南中提到,“The analog input pins can be used as digital pins, referred to as A0, A1, etc. ”。说的是,模拟输入口可以当数字口一样用。对于A0-A5来说,确实不错。但对于第一功能就...

你并不需要在调用analogWrite()之前为设置输入引脚而调用pinMode()。 The analogWrite function has nothing whatsoever to do with the analog pins or the analogRead function. 这个analogWrite方法与模拟引脚或者analogRead方法毫不相干 Syntax 语法 analogWrite(pin, value) Parameters 参数 pin: the pin to write to...

Arduino板上有多个模拟引脚（通常标记为A0-A5），可以用来读取模拟信号。In Arduino, analog input usually refers to the voltage value from the sensor, buttons, or other analog device through the analog pins of Arduino. There are multiple simulation pins on the Arduino board (usually marked as A0-A5...

Arduino Analog Pins There are six pins on the Arduino Uno (shown below A0 ~ A5) that can be selected for an ADC measurement; A multiplexor feeds one of the six analogue input pins into the ADC. Use the function: analogRead(pin)
int analogPin = 3; // potentiometer connected to analog pin 3 int val = 0; // variable to store the read value void setup() { pinMode(ledPin, OUTPUT); // sets the pin as output } void loop() { val = analogRead(analogPin); // read the input pin ...
