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); :将转换后的电压值通过串行通信发送到电脑的串行监视器,并换行。 硬件连接 电...

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 because this is how the analog inputs work.
