二、模拟引脚(Analog Pins) Arduino Nano有8个模拟输入引脚,编号为A0至A7。这些引脚主要用于读取模拟传感器的值,如温度、湿度、光强度等。 cpp // 读取模拟传感器值的示例代码 int sensorPin = A0; // 定义模拟传感器引脚 int sensorValue = analogRead(sensorPin); // 读取模拟值 三、特殊功能引脚 RESET(复...
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...

The Nano has 8 analog inputs, each of which provide 10 bits of resolution (i.e. 1024 different values). By default they measure from ground to 5 volts, though is it possible to change the upper end of their range using the analogReference() function. Analog pins 6 and 7 cannot be us...
