## Components

- **WIZnet W5100** x 1 ([docs](https://docs.wiznet.io/Product/Chip/Ethernet/W5100))
- Software: **Adafruit Circuitpython** ([docs](https://docs.circuitpython.org/en/latest/README.html))

## Description

Socket Visualizer is a [CircuitPython](https://circuitpython.org/) script that was created to help test the [WIZnet5k driver](https://github.com/adafruit/Adafruit_CircuitPython_Wiznet5k) provided by [Adafruit](https://www.adafruit.com/). It creates a simple server that listens for TCP connections and displays a table in the serial console containing hardware socket status information ('reservation' state, status and connected client) as connections are made and broken. When clients connect, the server sends a string indicating which hardware socket the client is connected to. While the client is connected, the server sends out 'heartbeat' strings every 2 seconds.

Below is an example of the Socket Visualizer's output:
