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
Reads an analog input and prints the voltage to the Serial Monitor. 读取模拟输入并打印电压值到串口监视器。 This example shows you how to read an analog input on analog pin 0, convert the values from analogRead() into voltage, and print it out to the serial monitor of the Arduino Software...

If the button is not pressed, Arduino will detect 1.You can also use the constants LOW, which maps to 0, and HIGH that maps to 1.This value can be printed to the serial output, like in this program:#define BUTTON_PIN 3 void setup() { pinMode(BUTTON_PIN, INPUT_PULLUP); Serial....
