例如,当A0引脚的电压为0V时,返回0;当电压为5V时,返回1023。 float voltage = sensorValue * (5.0 / 1023.0);:将读取到的模拟值转换为实际的电压值。公式如下: voltage=sensorValue×(1023.05.0) - 这里假设Arduino的参考电压为5V,模拟输入的分辨率为10位(0到1023)。 Serial.println(voltage); :将转换后的...
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...

The microcontroller of the board has a circuit inside called ananalog-to-digital converterorADCthat reads this changing voltage and converts it to a number between 0 and 1023. When the shaft is turned all the way in one direction, there are 0 volts going to the pin, and the input value ...
