2、模拟输入 - Analog Input In this example we use a variable resistor (a potentiometer or a photoresistor), we read its value using one analog input of an Arduino board and we change the blink rate of the built-in LED accordingly. The resistor's analog value is read as a voltage becau...

Today, the editor will bring you"Learning Arduino"Welcome to visit!思维导图Mind mapping在Arduino中，模拟输入通常指的是通过Arduino的模拟引脚读取来自传感器、按钮或其他模拟设备的电压值。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 v...
