Video 42: How to Send Data to the PC over WiFi or Ethernet Using UDP

The video demonstrates how to set up client-server communication between a Raspberry Pi and a PC using Python and UDP (User Datagram Protocol). It covers the creation of both server and client programs, initialization and binding of sockets, data exchange, and basic functionality implementation.

1. Introduction to Client-Server Communication: Understanding the need for cleaner remote connections.

2. Server Program Creation: Step-by-step guide to creating a server program on Raspberry Pi using Python’s socket library.

3. Socket Initialization and Binding: Learning how to initialize and bind sockets for communication.

4. Data Exchange: Exploring the process of sending and receiving data between the PC and Raspberry Pi.

5. Client Program Creation: Discovering how to create a client program on the PC side to communicate with the Raspberry Pi server.

6. Server Address Setup: Specifying the server address (Raspberry Pi’s IP) in the client code.

7. UDP Client Creation: Utilizing the socket library to create a UDP client on the client side.

8. Communication Initiation: Initiating communication by sending requests from the client to the server.

9. Request Handling on Server: Processing client requests and sending back responses on the server.

10. Data Decoding: Decoding received data using UTF-8 encoding for readability.

11. Basic Functionality Implementation: Demonstrating bidirectional communication with a simple example of counter manipulation.
