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...
Arduino Due does not have an analog output voltage from 0 V to Vref, but from 1/6 to 5/6 of the reference voltage, that is, 0.55 V and 2.75V with Vref = 3.3 V. This is also confirmed by the Atmel (see bibliography). The output voltage range of the DAC is only 2.75-0.55 = 2...

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 voltage value from the sensor, buttons, or other analog device ...
