2、读取模拟电压 - Read Analog Voltage 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...
begin(9600); // 初始化串口通信 } void loop() { sensorValue = analogRead(analogInPin); // 读取模拟输入的值 voltage = sensorValue * (5.0 / 1023.0); // 将模拟输入的值转换为电压值 // 打印输出 Serial.print("sensor = "); Serial.print(sensorValue); Serial.print("\t vol = "); ...
