Example Arduino Code for Battery Monitoring

If you are using this battery with an Arduino UNO for monitoring purposes, you can use the following code snippet:

// Battery Voltage Monitoring Code
const int batteryPin = A0; // Analog pin connected to battery voltage divider
float voltage = 0.0;        // Variable to store battery voltage

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

void loop() {
  int sensorValue = analogRead(batteryPin); // Read the voltage
  voltage = sensorValue * (5.0 / 1023.0) * 2; // Convert to voltage (adjust divider)
  
  Serial.print("Battery Voltage: ");
  Serial.println(voltage); // Print the voltage to the Serial Monitor
  
  delay(1000); // Wait for 1 second before next reading
}

This code reads the voltage from the battery and prints it to the Serial Monitor. Make sure to adjust the voltage divider as necessary for accurate readings.
