Connect the battery to the Arduino Uno board:

1. Connect the positive terminal of the battery (red wire) to the VIN pin on the Arduino Uno board.
2. Connect the negative terminal of the battery (black wire) to the GND pin on the Arduino Uno board.

Example 2: Raspberry Pi-Based IoT Project

In this example, we will demonstrate how to use the Witty Fox 11.1V 2000mAh Li-Ion Battery to power a Raspberry Pi-based IoT project. We will connect the battery to a Raspberry Pi 4 model B, which will run a Python script to monitor the battery voltage.

Hardware Requirements:

Witty Fox 11.1V 2000mAh Li-Ion Battery
 Raspberry Pi 4 model B
 Breadboard
 Jumper wires
 Voltage sensor module (optional)

Code Example:
```python
import os
import time
import RPi.GPIO as GPIO

# Set up GPIO mode
GPIO.setmode(GPIO.BCM)

# Define the voltage sensor pin
voltage_pin = 17

# Set up the voltage sensor pin as an input
GPIO.setup(voltage_pin, GPIO.IN)

while True:
    # Read the voltage sensor value
    voltage_value = GPIO.input(voltage_pin)
    
    # Convert the voltage value to a readable format
    voltage = voltage_value  11.1 / 1024
    
    # Print the battery voltage
    print("Battery Voltage: {:.2f}V".format(voltage))
    
    # Wait 1 second before the next reading
    time.sleep(1)
```
Connect the battery to the Raspberry Pi 4 model B:

1. Connect the positive terminal of the battery (red wire) to the 5V pin on the Raspberry Pi 4 model B.
2. Connect the negative terminal of the battery (black wire) to the GND pin on the Raspberry Pi 4 model B.
