也正因为此，在 Arduino 的官方指南中提到，“The analog input pins can be used as digital pins, ...
it consists other components such as crystal oscillator, serial communication, voltage regulator, etc. to support the microcontroller. Arduino Uno has 14 digital input/output pins (out of which 6 can be used as PWM outputs), 6 analog input pins, a USB connection, A Power barrel...
This naming system is similar to what was used on many classic AVR cores but here, they are just #defined as the corresponding Arduino pin number. If you need to get the analog channel number on a digital pin, use the digitalPinToAnalogInput(pin) macro - but you only need that if you...

to a costly design trade-off or a more costly microcontroller upgrade. The One Pin Keypad module eliminates the need for all of these digital inputs. As its name implies, One Pin Keypad uses only one pin (an analog input) plus GND and VCC connections, so wiring your keypad is a snap!
Control Arduino, ESP8266, ESP32, NodeMCU, and other microcontrollers with the smartphone over the Internet. Bluettoth and BLE are also supported. You can easily implement your projects through the interface prepared by connecting your digital or analog modules to your cards. ...
