To measure voltage, you first need to set up your Arduino sketch. A simple code snippet can help you read voltage levels. Here’s a basic example:
“`cpp
const int analogPin = A0; // Pin connected to the voltage source
float voltage = 0;
void setup() {
Serial.begin(9600); // Start serial communication at 9600 bps
}
void loop() {
int rawValue = analogRead(analogPin); // Read the analog input
voltage = (rawValue / 1023.0) * 5.0; // Convert raw value to voltage
Serial.print(“Voltage: “);
Serial.println(voltage); // Print voltage to Serial Monitor
delay(1000); // Wait for 1 second before the next reading
}
“`
In this code, `analogRead(analogPin)` captures the voltage signal from A0 and converts it into a raw integer value between 0 and 1023, as previously mentioned. Subsequently, the raw value is transformed into a voltage using the established formula. Remember that the reference voltage (Vref) is set to 5V for many Arduino boards; if using a different reference, adjust your calculations accordingly.
