After setting up the development environment and ensuring that necessary libraries like VLC for Python and RPi.GPIO were installed, I modified the code to play a video instead of an audio file and stop when GPIO pin 23 is grounded.

The results were satisfactory. The Raspberry Pi Zero W successfully played the selected video without issues and responded correctly when GPIO pin 23 was grounded, effectively stopping the video playback.

Advantages of Raspberry Pi Zero W: Compact size, Integrated wireless connectivity, Low cost, Adequate power for simple applications.

Disadvantages of Raspberry Pi Zero W: Lower processing power, Fewer ports, No standard video output.

Differences with other development boards: 

Raspberry Pi 3B+ and 4: More powerful, more ports, and offer a more comprehensive experience in terms of connectivity and performance, but they are larger and more expensive. Arduino: Unlike Raspberry Pi, Arduino focuses on low-level controllers and is more suitable for projects requiring direct interaction with sensors and actuators, while Raspberry Pi is more suitable for applications needing a full operating system and more advanced computing functions. ESP32: Similar to Raspberry Pi Zero W in terms of size and wireless connectivity, but it focuses more on IoT applications and has less general computing capacity than a Raspberry Pi.
