/*Analog InputDemonstrates analog input by reading an analog sensor on analog pin 0 andturning on and off a light emittingdiode(LED) connected to digital pin 13.The amount of time the LED will be on and off depends on the value obtainedby analogRead().The circuit:- potentiometercenter pin ...
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...

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...
Tx:Transmission pin for USART; can function as GPIO Rx:Receiver pin for USART; can function as GPIO Analog Pins:Eight analog pins which can also work as digital pins. These pins include (D14 (A0) — D21 (A7)) 2.3. Analog Input Pins (ADC Pins) ...
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. pin:输出的引脚号 ...

Arduino boards have multiple GPIO pins depending upon the board, some of the pins are analog which are connected to on board 10 bit-ADC (analog to digital converter). Analog pins can also be configured as digital ones. Arduino programming uses different functions to declare input output pins....
