What you need

• DC0-100V 50A red + blue and 50A Double Shunt
• Arduino or compatible microcontroller
• Power cable
• Safety protections (optional)

Steps

1. Check the datasheet for your circuit specifications.
2. Connect the red lead to the + terminal of the shunt.
3. Connect the blue lead to the – terminal of the shunt.
4. Connect the + terminal of the ammeter to the + terminal of the voltmeter.
5. Connect the – terminal of the ammeter to the – terminal of the voltmeter.
6. Verify that the microcontroller is compatible with the output signals.
7. Upload the Arduino code to read the values.
8. Test the system with a known voltage source.

Example code

```
void setup() {
  Serial.begin(9600);
}

void loop() {
  float voltage = analogRead(A0); // Lettura tensione
  float current = analogRead(A1); // Lettura corrente
  Serial.print("Tensione: ");
  Serial.println(voltage);
  Serial.print("Corrente: ");
  Serial.println(current);
  delay(1000);
}
```
