#include <Arduino.h>// Define the battery voltage and capacity
const float batteryVoltage = 11.1;
const int batteryCapacity = 4000;void setup() {
// Initialize the serial communication
Serial.begin(9600);
// Print the battery voltage and capacity
Serial.print("Battery Voltage: ");
Serial.print(batteryVoltage);
Serial.println("V");
Serial.print("Battery Capacity: ");
Serial.print(batteryCapacity);
Serial.println("mAh");
}void loop() {
// Read the battery voltage using the Arduino's analogRead function
int sensorValue = analogRead(A0);
float batteryVoltageReading = sensorValue (batteryVoltage / 1023.0);
// Print the battery voltage reading
Serial.print("Battery Voltage Reading: ");
Serial.print(batteryVoltageReading);
Serial.println("V");
// Wait for 1 second before taking the next reading
delay(1000);
}
```### Example 2: Raspberry Pi Power Supply with PythonIn this example, we will demonstrate how to use the Witty Fox 11.1V 4000mAh Li-Ion Battery to power a Raspberry Pi using Python.```python
import RPi.GPIO as GPIO
import time# Define the battery voltage and capacity
battery_voltage = 11.1
battery_capacity = 4000# Initialize the GPIO library
GPIO.setmode(GPIO.BCM)# Define the GPIO pin for the battery voltage reading
GPIO.setup(17, GPIO.IN)while True:
# Read the battery voltage using the Raspberry Pi's GPIO library
sensor_value = GPIO.input(17)
battery_voltage_reading = sensor_value (battery_voltage / 1023.0)
# Print the battery voltage reading
print("Battery Voltage Reading: {:.2f}V".format(battery_voltage_reading))
# Wait for 1 second before taking the next reading
time.sleep(1)
