Code Examples

### Example 1: Arduino Uno Power Supply

In this example, we will demonstrate how to use the Witty Fox 11.1V 4000mAh Li-Ion Battery to power an Arduino Uno board.

```c++
#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 Python

In 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)
```

Safety Precautions

When handling the battery, avoid short-circuiting the terminals, as this can cause a fire or explosion.
 Keep the battery away from children and pets.
 Avoid overcharging or over-discharging the battery, as this can reduce its lifespan.
 Follow proper charging and discharging procedures to ensure safe and efficient operation.

By following these guidelines and code examples, you can effectively use the Witty Fox 11.1V 4000mAh Li-Ion Battery in your IoT projects.
