The following example demonstrates how to use the REF-14S with an Arduino UNO to provide a stable reference voltage for an ADC.
// Example code to use REF-14S with Arduino UNO
// This code reads the reference voltage and prints it to the Serial Monitor
const int refPin = A0; // Connect VOUT of REF-14S to A0
void setup() {
Serial.begin(9600); // Initialize serial communication at 9600 baud
analogReference(EXTERNAL); // Use external reference voltage
}
void loop() {
int sensorValue = analogRead(refPin); // Read the analog value from A0
float voltage = sensorValue * (5.0 / 1023.0); // Convert the analog value to voltage
Serial.print("Reference Voltage: ");
Serial.print(voltage);
Serial.println(" V");
delay(1000); // Wait for 1 second before the next reading
}
