Arduino计算并显示电压电流对应的有功功率

好的，我可以为您提供帮助。首先，您需要使用Arduino测量电压和电流值。然后，使用这些值计算有功功率。最后，将这些值显示在Arduino上，可以使用液晶显示屏或其他适当的显示设备。以下是一个基本的代码示例，可以让您开始编写您自己的程序：

// Define analog input pins for voltage and current measurements
int voltagePin = A0;
int currentPin = A1;

// Define constants for resistance and voltage scaling
float resistance = 10.0; // in ohms
float voltageScale = 5.0 / 1023.0; // based on 5V reference and 10-bit ADC

void setup() {
  // Initialize serial communication
  Serial.begin(9600);

  // Initialize LCD display, if using one
}

void loop() {
  // Read voltage from analog input pin
  int voltageReading = analogRead(voltagePin);

  // Read current from analog input pin
  int currentReading = analogRead(currentPin);

  // Convert voltage and current readings to actual values
  float voltage = voltageReading * voltageScale;
  float current = (voltage - 2.5) / resistance; // assuming a 2.5V reference for current measurement

  // Calculate power
  float power = voltage * current;

  // Display power value, if using an LCD display
  // ...

  // Print power value to serial monitor
  Serial.print("Power: ");
  Serial.print(power);
  Serial.println(" W");

  // Delay for a short period of time
  delay(1000);
}
